Hi Can anyone show me where the 4-speed "reverse indicator light" harness routes through the firewall ?
Thanks in advance Mike

Hole "B" is not punched on my '69 RR - 4speed with light but no factory tach - and it's an unrestored 17,000-mile car. Not much help on an AT car, though... Does your car have the "A" (I don't want to say it but I just have to ) hole?

Pun intended I guess it could route through either hole, and maybe the length of the harness would give me a hint. It may have to route through hole A.

The wires will be in two of the open spots in your bulkhead connection, Your service manual will show where the wires will go. The hole marked "B" is for the tach wire only.

Correct...it connects at bulkhead. Pretty sure it is one of the two bottom outside corners. A look at the wiring diagram will clarify it for you.

Hmmmmmm the only one that makes sense is "A". Maybe someone else can help? Reason I say that is my A12 is a 727 auto BUT my '69 GTX is a 4-Speed with a reverse light under the dash AND a tachometer and I "think" both the reverse light wire and the tach wire come through the firewall through the same LARGE hole but up and to the driver's side? Here's an ugly shot of what I think is the hole on the GTX for those wires for the reverse light and tach. Probably wrong on this but hope someone else will chime in. Mike too Sorry for the late response .... Hole A is where the throttle cable comes thru , B is the optional Tach. The reverse lights go thru the bulkhead connected to a wiring harness' empty holes ... same ones as the neutral safety switch for auto trans? ..... check your wiring diagram ...
running up my post count some more .
