Ignition switch wires identification
I've rewired my 75 Duster using EZ's Wiring harness. All is good but I'm having trouble getting the ignition switch wired properly. I replaced it with a new switch, only difference is there is one extra black wire which is smaller - I'm just not using it. My problem is I can start the engine but when the key goes back to "run" position it kills the engine, I lose +12v at the coil (in my case +12v to the MSD box I have).
My question, there are 5 wires and here's how I have them identified based on the wiring diagrams. What does each do? Based on the diagram I should be using the brown wire to the coil but my continuity test proves I have continuity from the red to brown in crank position but it opens in "run" position (which makes sense why it kills the engine in run mode)
Red - Main Power
Black - ? (have connected but not sure what this is)
Brown - Coil +
Blue - Alt & Voltage Reg
Yellow - Starter relay (start)
I have the brown wire feeding the + coil or in my case the 12v switched input to the MSD box.
Here's a few pics and my continuity test:
