engine harness 74 challenger
« on: January 18, 2015 - 03:16:06 PM »
ok I've looked at wiring diagrams looked through the threads and Im still lost maybe more so than when I started.

First of is the alternator I have the (black) (green) and (blue) hooked up but I have a (purple) plug and a (brown) wire that comes out of the same leg of harness and I have no clue...

on the other side close to the wiper motor I have a (grey), a (brown) and a (black/yellow) wire

and lastly closer to the fusable link  I have a three wire plug (black/yellow) (blue) and (yellow) I assume that's the seat belt thing

beside the three wire plug I have a dark grey wire aswell


thanks for any and all help

Dave

These are the alternator wires.

These 3 are coil wires

Tach wire from port number 20 on the fire wall side bulkhead to the coil is a grey/black stripe.
You can get them from Classic Industries where I bought mine.

The purple and brown wire coming out by your alt, one is for temp sensor and the other for the washer bottle motor. Purple for the temp if I remember right.
