Hi.

I'm in the process of wiring my Microsquirt, and i have a thick grey wire with IGN written on it. But i can't find it in the wiring diagram, can anyone tell me what this goes to?

Thanx

That wire is the co-axial wire for the crank sensing circuit. In my case it is VR1+ & VR1-, as I am using a VR sensor at the crank.
You can find this under "wiring" under the microsquirt.info pages, snap shot below...
Hope this helps.
