I'm finally getting around to wiring in the ignition control on my 1987 turbo II. I've been running fuel only for a few years now.

The instructions say to wire from led 18 to the IGs-T (coil select) on the coil and led 19 to IGt-T on the coil. My question is which wire on the 4 connection plug is IGs-T and IGt-T??? I've eliminated the Yellow w/blue wire. It is a tach/check plug wire. So I have the Blue w/ yellow wire from the "X" slot on the ECU plug, the Brown w/ yellow wire from the "U" slot on the ECU plu and the Blue w/ red wire from the "M" slot on the ECU plug.

Thanks in advance

 

I hooked up the CAS and the leading coil, and set up software and gave it crank. And, boy if didn't fire right up. It didn't run very good. I hadn't even looked at the spark table yet. But that sure made me feel good that it started.

Just need some help with the trailing coil.

I just found the info on the MS forum. For those that want to know: Led 18 IGs-T is hooked to the Brown w/yellow wire, and Led 19 IGt-T is hooked to the Blue w/ yellow wire.
