Ok, so I got a electronic wiring harness from a 71 Dart and am installing it on my 70 swinger. I have the diagram that shows which wire goes to what. Its a 5 pin connector on the ECU. So, two wires go to the dist, one goes to neg. on the coil, one goes to pos. on the coil, and the last goes to the ignition run wire. There lies my problem. Which wire is the ignition run wire and where can I find it?
