What goes in this plug? 70 cuda - 12/15/13 03:20 AM

I have one wire with a plug coming out of the firewall, in back of the brake booster, inboard side.
Nut sure what. Hooks up to this.
Any ideas?
Thanks

There are 2 seperate wires, coming out of that area.
This is the lower wire, not sure what the upper one is but it is plugged in the forward side of the fuse block.

Is it a 4speed car ??? It could be the safety switch wire from the clutch . . . it should go to the starter relay if so. You know, you have to depress the clutch pedal in order to start the car . . . according to FSM, should be a dark green wire

Cheers

Go to mymopar.com and look int he tech section you can download a wire diagram for free. I got several of them and put them on a stick went to Target printing and had 11X17 copies made, mulitples for each car that way I can draw on them to trace circuit if I want to. It cost me $8 for about 3 copies on 4 cars.

I just wired mine, it's a 4 speed and if you post a picture of which one you have a question on I can probably tell you if not one of the smart guys can.

Good luck.

My 73 has a gray with black tracer wire coming out of the firewall in that location. It's the tach wire and goes to the - side of the coil.
