SEAT BELT WARNING RELAY HARNESS

TECH NOTES:

SEAT BELT WARNING BUZZER
It is important to identify if your 1972 vehicle came from the factory with, or without the seat belt warning buzzer to avoid problems when rewiring your vehicle. Do not assume that because you don't hear the buzzer, that your vehicle did not come with one. This buzzer was often removed because the sound was annoying.

1972 introduced the seat belt warning buzzer to all GM vehicles. This buzzer was designed to audibly remind drivers to fasten their seat belt.

Some early 1972 production vehicles did not have a seat belt warning system.

Other early 1972 production vehicles used the following to control the seat belt warning system:
* Indicator Lamp (illuminated for a few seconds)
* Timer (located behind dash)

If your vehicle is setup this way, you should purchase the Dash Harness, Rear Body Harness, and/or other electrical items for the "WITHOUT seat belt warning buzzer" application.

Note: MOST 1972 production vehicles used the following to control the seat belt warning system:
* Indicator Lamp (illuminated until seat belt pulled from retractor)
* Warning Buzzer (located behind dash, sounded until seat belt pulled from retractor)
* (1) Seat Switch (located in passenger side seat cushion)
* (2) Seat Belt Retractor Switches (located in each front seat belt retractor)

If your vehicle is setup this way, you should purchase the Dash Harness, Rear Body Harness, and/or other electrical items for the "WITH seat belt warning buzzer" application.
