Midlife#1: brake master cylinder/proportioning valve plug
#2: Unknown. Note yellow wire added to main loom!
#3: seat belt relay on left; NSS/backup in middle, and engine gauge feed harness on right top. What's underneath the engine gauge feed harness is very strange, never seen that before.
No. There are some other wires, notably a white/black and a yellow wire into a four pin flat plug?
Oh! That's the repro guage harness.No. There are some other wires, notably a white/black and a yellow wire into a four pin flat plug?
+1#2 was the aux power wire
Used on cars with high draw power options
power window cars
auto seat release system
I think the light group too - under hood, trunk, map, glove box and under dash lights
I think #4 was a wire to the red under dash emission box on 73 cars
I'll see if I can find a clean route on the driver's side that allows the temp sensor and choke leads to connect. I have the coil mounted to one of the intake bolts forward of the carb, so the harness might just stay where it is.The coil choke and temp harness should be running along the driver's side of the intake.
That feed was used for power windows, power seat (Cougar), rear window defroster, power top (convertible only) and the automatic seat back latches.
