engine and drivetrain Sealt Belt Wiring Question

[lsixt]

1974 2002, manual transmission, AC, nothing else of any interest.

Carpet is ready to go in, but before I do that.... on the driver side there are two connectors for the seatbelt warning wiring, but then there is one more wire that comes out of the harness that I don't know.

Anyone know what that wire is for? It's brown with green stripe. The passenger side only has the two connectors for the seat and the seatbelt.

See photo.

Thanks,

Len

My guess is it is the wire that attaches to the e-brake mechanism. It is wired to light up the "brake" idiot-light on the dash when your e-brake is on. It is a single wire, and on a 76 at least, it is brown with blue stripes. After 33-years, I can see blue stripes becoming green stripes.

There are a pair of wires that run under the driver and through the tunnel to the backup switch on the tranny, but that is a pair and neither of those wires are brown.

The 76 diagram says there is an optional neutral (park) indicator switch that runs from auto tranny to the starter relay, and they are connected with a single wire which is brown with black stripes. I have no idea where this switch is, but it is possible the wire runs the same general route as the manual tranny backup wiring. Assuming they use the same harness for manual and auto trannies, then a manual harness will have an unused connector for this brown/black wire.

Finally, 02s with the green console button are pre-wired for a pax ejector seat. But it doesn't make sense for that wire to be on the driver side, so your mystery wire is unlikely for the e-seat.

e-brake makes sense....

I'll need to find the switch? it connects to though as there is no place I can see where it connects
