Original Design Series Wiring Harnesses

Exact OEM Reproduction Wiring Harnesses for Classic & Muscle Cars

What are our Original Design Series™ wiring harnesses?

Our Original Design Series™ wiring harnesses are manufactured exactly as the wiring was made when your vehicle left the factory. These harnesses are made to the exact O.E.M. (original equipment manufacturer) specifications, using the original factory blueprints, and are factory-correct in every way. These are full-assembled, ready to install, “plug & play” accurate reproduction wiring harnesses. You will NOT have to cut any wires, crimp any terminals, or make any modifications to these harnesses when installing them in your classic car or truck.

Are these wiring harnesses the right choice for you?

Are you keeping your vehicle all factory-original? If you want to rewire your vehicle to its stock configuration, the way it was when it left the factory, the choice is simple. Our Original Design Series™ wiring is the right choice for you. It doesn’t matter if your vehicle will be a "driver" or judged at a prestigious car show, these wiring harnesses fit the bill.

You can also purchase additional wiring harnesses if your vehicle had factory-installed (not dealer installed or aftermarket) options. For example: air conditioning, power windows, rear window defogger, power top, etc. These additional harnesses will plug directly into the main harnesses as they did at the factory. With our Original Design Series™ wiring, you can either rewire the vehicle one harness at a time, rewire a specific area of the vehicle (for example, the engine compartment), or what we recommend, completely rewire the vehicle bumper-to-bumper by purchasing all the harnesses at one time; and save 10% off your entire purchase!

Are you keeping your vehicle mostly factory-original (with specific modifications)? Do you want to retain most of your vehicles originality but want to make some updates/modifications, specifically:

  • Are you moving the alternator to the opposite side?
  • Are you replacing an externally regulated alternator/generator with an updated internally regulated alternator?
  • Are you adding General Motors' HEI electronic ignition?

If you've answered "yes" to any of these questions, we may have a solution for some year/make/model vehicles. Due to the popularity of these updates, we may offer a modified wiring harness, conversion wiring harness, or conversion device to accommodate these updates. In this situation, we recommend that you purchase our Original Design Series™ wiring and the appropriate conversion product(s). Please consult our online catalog to check availability on your specific make & model vehicle, or call our technical support department for more information. For faster, easier installation, we recommend starting with an electrically sound foundation by choosing the Original Design Series™ wiring. Rewiring the entire vehicle as-original. Then making the necessary modification yourself. Keep in mind that many of the added aftermarket devices you purchase (like gauges, lighting, electric fans, etc.) come with their own wiring. All you need to do is to tap into your wiring harness to add those devices.

With our Original Design Series™ wiring, you can either rewire the vehicle one harness at a time, rewire a specific area of the vehicle (for example, the engine compartment), or what we recommend, completely rewire the vehicle bumper-to-bumper by purchasing all the harnesses at one time; and save 10% off your entire purchase!

You can also purchase additional wiring harnesses if your vehicle had factory-installed (not dealer installed or aftermarket) options. For example: air conditioning, power windows, rear window defogger, power top, etc. These additional harnesses will plug directly into the main harnesses as they did at the factory. With our Original Design Series™ wiring, you can either rewire the vehicle one harness at a time, rewire a specific area of the vehicle (for example, the engine compartment), or what we recommend, completely rewire the vehicle bumper-to-bumper by purchasing all the harnesses at one time; and save 10% off your entire purchase!

What is involved in the installation of these harnesses?

Of all the different wiring series we offer, these Original Design Series™ wiring harnesses are, by far, the fastest and easiest to install. Unlike our RestoMod Series™, Classic Update Series™, or Street Rod Series™ wiring systems which are basically one big (front-to-rear) wiring system, our Classic Design Series™ reproduction wiring is manufactured (as original) as individual harnesses. Meaning, there is an engine harness, a dash harness, a forward lamp/front light harness, a rear body harness, etc. All of these individual harness are sold separately, installed separately, and plug into each other to complete the entire electrical system of the vehicle. We recommend that you install your new harness as you are removing your old one. This way, you can be more certain that the wires are routed as original and that the wires are going to their intended devices. Please see our FAQ page for more information about installation options.


 

Our wiring harnesses are brand-new and better than N.O.S. (new old stock)

THE PROBLEM: Let's face it folks, NO automobile manufacturer ever designed a wiring harness to last 30-60 years. As a matter of fact, your vehicle's original wiring was only designed to last 10 years before it started to deteriorate! There is ample documentation to substantiate this claim.

Even if you think your wiring "looks good", it's probably not. Your wiring is made of copper wire with a covering of plastic (mostly PVC) insulation. This insulation is porous. Contaminants, like oxygen, moisture and airborne pollutants, eventually pass through the insulation to attack the wire; a condition called oxidation. There is no practical way to completely seal off the circulation of oxygen and moisture between the individual wire strands. Once the wire strands become oxidized, the internal resistance of the wire increases substantially. The same oxidation/corrosion factor will happen to the wire's metal terminals over time; further increasing the internal resistance of your wiring harness. Even if you are lucky enough to find an N.O.S. (new old stock) wiring harness, the wire strands have probably deteriorated over time just by sitting in a bag on a shelf. For this reason, it would NOT be wise to purchase an N.O.S. harness. This is not a good thing for any electrical system.

If your wire has advanced to the next stage of deterioration by being brittle and cracking (especially evident in an engine compartment where high heat and moisture are constant), it is in immediate need of replacement. At this stage, a short circuit to ground is eminent. In a worst case scenario, it can cause a vehicle fire.  Not a good day if your car is stored in your garage!

THE SOLUTION: Get rid of your vehicle's electrical problems, or potential problems, by replacing all the wiring with new wiring harnesses. But, before you buy a wiring harness for your show car, restoration, or weekend driver, ask yourself, "Is it a Lectric Limited wiring harness? "

How are wiring harnesses made

Our Original Design Series™ Wiring Harnesses are:

A. Built to the Original Blueprint Specifications

Our extensive library of obsolete original manufacturer's automotive blueprints insure that all our harnesses are built to the correct specifications. This is the only way to insure that you won't have a problem with the installation or operation of your new harness.

B. Built with Correct Wire

  • Wire Type (highest-quality automotive GPT/GXL/SXL, fuse link, hi-temperature, or resistance wire)
  • Wire Color (we NEVER "cheat" by using a colored die over white insulation. Our wire insulation is a solid color extrusion)
  • Wire Gauge (we NEVER "cheat" by using heavy-wall insulation then reducing the diameter of the actual copper core)
  • Wire Striping Color (white, colored, or cross-color)
  • Wire Length and Strip Length

C. Built with Correct Terminals

  • Original or Original-Reproduction Terminals (Many original terminals have become obsolete.  To maintain originality and functionality, we have invested in tooling to reproduce these terminals)
  • Method of Terminal Application. (We machine crimp our terminals. Machine crimping, unlike hand crimping, uses a 3 to 5 ton press to apply terminals so they won't fall off. Terminals (if called for) are then dip soldered. Terminated wire is also randomly put through a digital pull-testing machine as an added quality control procedure.)

D. Built with Correct Connectors

  • Connector Type (Many original connectors have become obsolete.  To maintain originality and functionality, we have invested in tooling to reproduce these connectors)
  • Connector Color and Material

E. Built with Correct Lamp Sockets

  • Lamp Socket Design, Functionality and Material (when possible)

F. Built with Correct Grommets

  • Grommet Color
  • Grommet Size (O.D. & I.D), Material and Durometer
  • Grommet Orientation

G. Built with Correct Clips & Clamps

  • Clip Type
  • Clip Color, Material and Durometer
  • Clip Placement
  • Clip Orientation

H. Built with Correct Tape

  • Tape Type (adhesive, non-adhesive, hi-temperature fiberglass or cloth)
  • Tape Color
  • Tape Width
  • Tape Wrapping (Most of our harnesses are wrapped using an automated taping machine (as original), as opposed to hand taping. Machine taping insures uniform tape tightness and overlap/spacing.

I. Built on a Wiring Harness Assembly Board

We assemble all our wiring harnesses on a wire harness assembly board to insure that each harness is consistently made accurately, with the correct: break-out positions, lengths of wires at each break-out, harness fastener locations, and taping locations. This method of assembly also insures that your harness will fit correctly and reach where it needs to go.

J. Quality Control Tested with a Digital Circuit Analyzer

Fully Circuit Analyzed!  Every harness built by Lectric Limited is fully circuit analyzed.  To do this, our assembly boards are back-wired to a circuit analyzer. While your harness is being built, our digital circuit analyzers continuously checks: continuity (or breaks in continuity), missing wire(s), mis-wires, mis-indexed wires, splice integrity, and scans for short circuits of EACH circuit of the harness. We are the ONLY reproduction wiring harness company in the world that circuit analyzes every harness we build! This is the ONLY way to ensure that your harness will work BEFORE you install in your car. After all, you don't want to have to tear-out a brand-new harness, after spending hours or days on installation, because it's defective (and could be a fire hazard). Buy your circuit-tested wiring harnesses from Lectric Limited and you won't have to worry about an incorrectly made harness.

We've invested thousands of dollars into new state-of-the art circuit analyzers to replace our older testing system. Did we need to purchase new testing equipment? Not at all. But since circuit analyzing is one of our best selling points, we want to be sure our testing standards are current. This way you can be certain that your harness will function perfectly BEFORE you install it!

Many original Packard Electric® terminals and connectors are quickly being discontinued. This makes it increasingly difficult to produce an authentic reproduction wiring harness. However, Lectric Limited is meeting this challenge by producing its own tooling and molds to replace many obsolete components, this way our harnesses continue to meet the most rigid demands of the enthusiast. On rare occasions, however, we may require our customers to use a connector from their original harness to preserve originality and/or functionality.

If you need ALL the wiring for your vehicle, you can save 10% off your entire purchase!

Donor-Required Wiring Harnesses

donor wiring harness

What do we mean by a "donor harness"?   In our online catalog, if there is a notation that "...customer must provide a useable (component) ", this means that we will need to use one or more components from your old (donor) harness to manufacture your new wiring harness. Of course, the remainder of the components (wire, terminals, connectors, clips, tape, etc.) will all be brand new when you receive your manufactured harness.

Why do we sometimes require a donor harness?  Some of the unique components required to manufacture your new harness are no longer being produced, and are no longer available. Without these essential components, your harness can not be manufactured. The needed components, usually unique connector(s), fuse block, or bulk head connector (the bulk head connector is the one that goes through the firewall), must be good condition and not broken.

How often is a donor harness required by the customer?  Not very often. But it happens. Only about 2% of the wiring harnesses we offer require a donor harness.

What should you do (and not do) if a donor harness is required?  If possible, do NOT cut the harness or remove any component prior to shipping. Send us the ENTIRE (specific) harness.  We ask this because there have been instances where the customer has damaged an obsolete component when trying to remove it from their old harness. Or instances where we needed more components from the original harness than initially thought; resulting in delay time and multiple shipping charges incurred by the customer.

What will we do with your donor components?  Upon initial inspection, if it is determined that the component required to make your new harness is in good condition, not broken or about to break, our technicians will carefully remove the component with the proper tools. Upon manufacturing your new harness, if a connector was used from your donor harness, we will replace all the metal terminal(s) with new ones. If a fuse block was used, we will replace all the fuse clips and terminals within the fuse block, with new ones.  Please note and understand, if it is later determined that we cannot use the component from your donor harness, even after we initially thought we could, we will not be able to make your harness.  At that time, we will contact you and return your non-usable component and donor harness to you. Although it is extremely rare that this can happen, it can happen.  If you place an order that requires components to be provided to us, we will contact you with additional information at that time.

Harnesses that require a donor harness include, but may not be limited to, the Original Design Series™:

  • Buick Full-Size Power Window Harness
  • Buick Skylark/Special (1964-67) Dash Harness
  • Buick Skylark/Special Power Window Harness
