Leading Ignition Problem from E6k
 

Ok, I’ve been tracing my leading ignition problem for awhile now and I think I may have found the answer, but I need your guy's help.

Right now the leading ignition is not firing; however the trailing is working fine. The leading coil was swapped with a known good one and both were tested. The Igniter was also swapped with a known good one. The harness between the igniter and the coils checked out ok. Then I checked from the igniter plug to the stock ecu plugs for continuity of the light green wire. It was fine. So then I was looking at where the light green wire would plug into the haltech and there is no pin in the spot for the light green wire. I think this is a K2RD harness for the haltech, but I’m not sure as it was installed when I purchased the car.

I looked at the attached diagram and it looks like pin 36 is the one that should be connected to the light green wire (leading ign). However the harness has pin 36 running off somewhere else that is labeled "Tach (2B)."

So does anyone know what’s going on here? It seems to me that pin 36 should be connected to the light green wire that goes to the igniter but then again I don't know if it is supposed to go to the tach. Is this a bad harness or am I looking in the wrong spot.

Thanks in advance, I hope I made sense, all these wires are racking my brain.

I figured it out and I was mostly right in my ramblings above. Whoever orginally wired up the E6k wired the ING OUT (pin 36) to the Yellow/Blue wire that goes to the tach, but did not wire it to the Light Green wire that goes to the igniter. I wired up the Light Green wire to the ING OUT and now I have leading spark. A lot of problems for such a stupid little error.
