Unless noted, all of our Original Design Series™ wiring harnesses include brand-new wire, terminals, connectors, tape, etc.  If the wiring harness you have is in need of repair, we recommend replacing it with one of our new, circuit-tested wiring harness.  However, although not the best option, we understand that there are times when repairing a harness is a budget-friendly option.  For this reason, we offer some pigtails, connectors and components to repair original wiring harnesses.

Please Note: The ONLY wiring harness repair items we offer are those shown in our online catalog. We do not offer any other repair items like connectors, terminals, lamp sockets, clips, fuse link wire, resistance wire or lead wires.

Shown below are some of the repair components we offer.  To see all of our repair components, see our online catalog for your application & price.

These Corvette Fuse Block Repair Kits include a new fuse block, buss bars and fuse clips. They do not include the Bulkhead Connector. (see Bulkhead Connector Repair Kit below). Fuse Block Repair Kits are vehicle-specific and are not available for other make/model vehicles. Check our online catalog for availability.

NOTE: It is difficult to replace your existing bulkhead connector, especially if your old harness is still in your car. Each terminal in this kit must be perfectly crimped or they will be destroyed and not seat, or lock into the connector. In addition, there will be limited slack (if any) in the wire after your old terminals removed.  Knowing this, we strongly encourage you to purchase a new, complete Dash Harness instead. A new dash harness (for most cars) will include a new fuse block, new bulkhead connector, new connectors & wire, and be circuit tested.

There are NO returns, exchanges, replacement of components that may have broken during installation or technical support on this item.  We ensure that there are no missing components prior to shipping. Use the “Fit My Vehicle” selection above to shop repair components for your specific vehicle.

The bulkhead connector attaches to the back side of the fuse block, in the engine compartment. These Corvette bulkhead repair kits include a new connector, terminals and firewall gasket.

Over the years, because of the lack of accurate replacement temperature sending units, car owners and mechanics were forced to improvise. After finding a sending unit that adequately worked, they would cut-off the original terminal & connector from their harness and splice-on one that mated to their new sending unit.

Since Lectric Limited now offers accurate temperature sending units (for many G.M. vehicles), made from the original General Motor’s blueprints, car owners want to restore their lead wire to the way it was originally.  With this kit, you can repair your temperature sending unit lead wire and get it back to the way it originally looked and functioned.

Kits includes new asphalt-dipped loom (for most applications), correct gauge & color wire, correct terminal and correct connector.

Through the years, car owners and stereo shops have cut-off and discarded the original radio and speaker terminals and connectors in order to install an alternative radio/stereo system.

So what is the restorer to do when he wants to install an original Delco® radio and/or Delco-Bose® radio & speaker system, but can’t find the original-type connectors? Of course, you can purchase a dash harness or optional radio/speaker harness which includes new wiring, terminals & connectors, or the budget-minded restorer can use one of these repair solutions.

With these pre-assembled repair pigtails, you can simply splice into your existing dash harness or speaker harness and you’re back to original!

Wire leads are correctly color-coded for easy identification and installation.  The image to the left depicts only a small portion of the radio repair components we offer.

Does your Corvette suffer from non-working or dim fiber optics? It’s not uncommon. In fact, after more than fifty years, many owners notice that the once-bright indicators on the console barely glow—or don’t light up at all. But before diving into repairs, it helps to understand exactly what the fiber optic system is and how it works.

Think of a fiber optic cable as similar to copper wire. The difference is that instead of carrying electricity, a fiber optic cable carries light. When light enters one end of the cable, it travels through the clear plastic fiber and exits at the other end. As long as the cable is clean, intact, and properly aligned, that light will transmit efficiently from one end to the other.

On 1968–1971 Corvettes, Chevrolet used this technology in a unique way. The fiber optic monitoring system was designed to give the driver a quick visual confirmation that key exterior lights were functioning properly. Rather than relying on electrical sensors, the system simply “borrowed” a small amount of light directly from the bulbs themselves.

The front fiber optic system monitors the headlights—both low beam and high beam—as well as the front turn signal lamps. The rear fiber optic system monitors the brake lights and the license plate light. Each of these bulbs has a small optical pickup that captures some of the light being produced. That light is then transmitted through a fiber optic cable to a display panel on the center console.

At the console, each monitored light is represented by a small colored indicator lens. When the bulb is operating, light travels through the fiber optic cable and illuminates its corresponding lens. If a bulb burns out, the light signal disappears and the indicator lens remains dark, alerting the driver that something needs attention. For its time, it was a clever and sophisticated system—one that added both function and a bit of futuristic flair to the Corvette interior. When everything is clean and properly aligned, it’s actually a very neat feature to see in operation.

Of course, time can take its toll. Over the years, fiber optic cables can become cloudy, kinked, or damaged. The small ferrules and ends can crack, loosen, or fall out of alignment. Dirt, oxidation, and general wear can also reduce the amount of light reaching the console indicators. When that happens, the system may work poorly, appear dim, or stop working entirely—which can be frustrating for owners trying to keep their Corvette operating as it did when new.

A common question is whether fiber optic cable can be repaired. In most cases, the answer is no. Properly joining fiber optic cable requires a specialized and expensive tool known as a fiber optic fusion splicer, which precisely fuses the ends together. Without this equipment, attempts to splice fiber optic cable typically result in a significant loss of light transmission. While a crude splice might allow some light to pass through, it will rarely transmit the same amount of light as an unbroken, continuous cable.

If the ferrules or cable ends are damaged, however, there is good news. We offer a practical repair solution that allows you to restore some of the cable ends without replacing the entire assembly.

And if you would prefer to replace only the front or rear fiber optic cable sub-assembly—rather than the entire wiring harness that contains it—we have a solution for that as well. A new fiber optic sub-assembly can be installed and neatly taped alongside your existing front lamp harness or rear body harness, restoring proper light transmission to the console indicators.

That said, if you are considering replacing only the fiber optic cables, it’s worth thinking about the bigger picture. For roughly the same amount of labor—and not much more cost—you can install a new forward lamp harness or rear body harness. These complete harnesses include a brand-new fiber optic sub-assembly along with new wiring, terminals, connectors, and insulation. In many cases, this approach not only restores the fiber optic monitoring system but also improves the reliability of the entire wiring system.

One of the most annoying problems with wiring harnesses as they get older is non-working or intermittently working light bulbs.  The problem is almost never the bulb, but is either the light socket, oxidized terminal connection, marginal terminal spring-tension, or combination of these factors.

Lectric Limited now provides light bulb repair components for many popular applications.  The image to the left depicts only a small portion of the light bulb repair components we offer.

This is the correct non-adhesive tape that was originally used to wrap automotive wiring harnesses. Unlike regular electrical tape, this tape does not have adhesive. It will not melt in the high-temperature engine compartment, or slime-over after a period of time. This tape clings to itself when overlapped.

Wiring Harness Repair tape comes in a 100 ft. roll and is available in 3 widths: 3/4″, 1″ or 1-1/4″. The 3/4″ roll is recommended when wrapping a small diameter harness (10 wires or less for example). The larger diameter roll can be used when wrapping a dash harness or similar, large diameter harness.

If you need to repair part of your wiring harness that requires a special tape, Lectric Limited offers both the fiberglass and cotton cloth tape.

High-temperature black fiberglass adhesive tape was commonly used on transistor ignition harnesses or on parts of a harness that route in areas exposed to high temperatures, near exhaust manifolds, over intake manifolds, etc.  Available in a 1″ x 100′ roll.

Cotton cloth adhesive tape was commonly used on rear body wiring harnesses. During factory installation, sections of the wiring that were pulled through areas with sharp edges were protected by the use of this tape. This tape has a marginal adhesive backing.  Available in a 1-1/4″ x 100′ roll.

When repairing a wiring harness, it is essential that the terminals have a proper crimp. Using long-nose pliers to crimp the terminals is not the best solution.  Our terminal crimper set is the better choice.

Note: When installing our replacement bulkhead connectors, it is imperative that the terminals in this kit are properly roll crimped. If not, the terminals can be distorted. If this occurs, they will not be able to be inserted into the bulkhead connector and may be ruined.

These terminal crimpers will be able to crimp the majority of terminals used on ’50-’80s American-made vehicles.  They can be purchased individually (part #93963819 for smaller 20-14 gauge wire terminals or part #12040070 for larger double-wire/10-12 gauge wire terminals), or as a complete set (part #93963818). Crimpers are not intended for use with Weather-Pack or Metri-Pack terminals requiring rubber seals.
