I bought an aem v1 and the harness is pretty much plug and play but I'm having trouble identifying one wire that goes to the body harness side connectors(starter,clutch switch,ignition switch etc)...

The one I'm having trouble identifying is the IG-1 to m1 pin 4...I looked at the pinout on the ecu and the aem but no luck..I don't want to unravel the harness to find one wire but if I have to so be it

I ended up tracing the wire down to the igniter tach wire...so I guess the question now is which wire do I get the tach output from?..

Oh yeah this is on a 89 mk3
