1967 Ignition Wiring Harness
I recently purchased an engine harness cable to replace the hacked into and cracked harness. I didn't pay attention that the hacked into cable had a brown wire wired into the coil wire on the harness. I chased that brown wire through the firewall and found that it attached to the ignition switch.
I have the 67 Ford Repair Manual, but it does not present a clue about my problem. My ignition switch has this square (Circuit, Resistor) what ever it is at the rear of the ignition switch. There appears to be a center post with a galvanized bar attached to it that this (Circuit, Resistor) unknown thing is attached to.
It is a small box, maybe 3/4" in length and 3/4" in width, that has two posts on it. One post is marked yellow and other is red. The hacked into engine cable or additional brown cable is attached to the yellow post on the small box.
I tested the new cable, the car will turn over and appears to start, but will die once I let go of the key turned to start the car. When I put the hacked into cable back in place the car starts and runs fine. I was hoping to return the wiring to original, but I'm lost at this point.
