can anyone tell what this wire is for? it's located under the passenger seat.

Color? Can you tell us where you see it going to on either end?

looks like it could be the wiring for the emergency brake light on the dash.

Year etc???

The passenger seat had a pressure switch mounted in the springs for the passenger seat to turn on the seat belt warning light if someone was sitting in the seat. It could be the wiring for that switch.

jlp

it's a 72 build date 10/71. straps, no springs under seat. i think it's for the emergency brake. could it be a speaker wire or does that run under the rocker?

The speaker wire is buried in the bundle running along the right side rocker and disappearing into the dogleg. Check your parking-brake and find the button switch under the handle. There should be a single wire attached to it. The switch goes to ground when the parking-brake handle is lifted, this turns on the light on the dash. As a test, ground your mystery wire with the ingnition on and see if the brake light on the dash comes on.

Wiring for the ejection seat squib.

Oh crap! You had to go and spoil the surprise.

A Z car owner was launched today into low earth orbit due to a wiring malfunction, news at 11.

Only wire in my 1970 model in that location is the emergency brake switch for the red warning light in the speedometer.
