On my 2008 LMM I cannot find a lead on the engine harness that fits the alternator (2 pin) is there a short pigtail that plugs into the harness?
Alternator lead?

I cannot find this pigtail, anyone have a source for these?
Actually I cannot find the connector on my harness, according to the manual I have there should only be two wires going to it, a brown and a grey, if I could find it I can simply cut it off and wire directly to an aftermarket pigtail which I have, looks like it was only there in case someone purchased the dual alternator setup, I plan on having two alternators but the second I am going to try and convert to 24V for the dual voltage system on my HMMWV so there would be no connection to the ECM
UPDATE, I think I found it, it is just a 2 pin connector that is actually smaller than the alt. plug, has one brown and what looks like a cream/yellow wire, What is not helpful is the schematic shows the connection to the X2 connector at the ECM, not the harness connector where I can trace it out, this is REAL frustrating, looking at the pin-outs (connector views) of X107 and X108 I can find no reference to alternator, probably some stupid acronym that only makes sense to them.....Found connector view of X2 pin 8 is the voltage sense (circuit 25) and pin and pin 38 is the gen. exciter (circuit 23)
BUT when you look at X107 and X108 there is NO such circuit numbers WTF this is freaking crazy screwed up!
