Yet another harness wiring question I am trying to finish up the wiring on my vortec swap into a 89 wrangler.
I have a few wires from the original GM harness that I am a little unsure about. All of them were labeled a few months ago using the diagrams on lt1swap site.
I hate to be such a dipsh!t , but just don't want to damage anything by hooking things up incorrectly. Thanks for any guidance.
D100 IGN 3V+ TP2 ----- not sure what this is for or where to attach
D3 PARK POSITION ----- D3 park position, should see a ground in park and neutral thanks nova
E11 IGN VOLT 0 --------- not sure what this is for or where to attach
F11 PARK STOP SIGNAL ------- unsure
C2 CHMSL SUPPLY VOLTAGE ------- brake light switch and is hot when brakes are appliedthanks nova
C1 OFF/RUN/CRANK VOLTAGE ------ 12V+ during crank and run thanks
C100 R ENGINE ON SIGNAL ------- unsure
again apologies if these are obvious or stupid questions, just need a little help. Thanks

D3 park position, should see a ground in park and neutral. C2 CHMSL hooks to the brake light switch and is hot when brakes are applied. Those are the two I know off hand, would have to look up the others but I'm not at home right now.
These harnesses are usually similar, but we do need to know what year engine , harness and PCM that you have.
That said, C1 OFF/RUN/CRANK VOLTAGE is an ignition wire to the PCM, it would be hot in run and start, or in other words, powered up by the ignition relay that is controlled by your ignition switch.
the rest I'm not sure about, where did you get the E11 F11 from?

D100 ign 3V TP2 I"m going to say is supposed to be C100? TP2 is an auxillary battery option, so you probably won't be needing that one.
E11 IGN is the ignition power for the PCM and auto trans.
F11 PARK STOP SIGNAL on my 2007 harness this goes to the range sensor on the side of the trans, you don't need it.
THe C100 ENGINE ON SIGNAL, I haven't traced it, but it goes to the instrument cluster. If I were you I would trace it and find out where the other end goes, tell me where it goes and I can tell you if you need it or not.

So is that C1 off/run/crank receiving 12v or giving off
I bought a diy fuse block and I have a wire asking for 12v in run and crank on ignition
do I hook it up to one of the wires off the ignition switch that is 12v run and crank? What do I do with the C1 off/run/crank wire
