first off, does anybody know where I can buy the female pins in the PCM harness?
I'm doing a LTCC setup, and as annoying as it it, I'm kinda a perfectionist when it comes to electrical (probably a good thing, on a chevy)
Anyway, it looks like the two power wires and the EST signal wire only went to the ignition. so I figured, why not just replace the wire all togather...

Think it will work

 

I think you may be better off just cutting the connector off the module, and coil and splicing it to the LTCC harness. But if you'd like to take it all the way to the PCM that's your choice, Trace the wire back to the PCM, and cut it short and splice it there. Finding the actual pins will be tougher than you think...You'll probably have to go to the dealership and hope the parts guys are competant enough to get you the right parts...

Just found them. very expensive. $12 for 3 of them. Might as well do it now. I guess I see the advantage being, if I ever wanted to pull it off and put my car back to stock(like to sell or something) I could do it easily.

in case anybody wants to know the GM p/n for PCM terminals on a 94 is 12084913

 

heh, umm.... also I found out the hard way that you can't do that with the pink wires. I still think it's worth doing with the white. I don't like the idea of splicing in to a wire that rely's on millivolts.

but those pink wires power other sensors as well (whoops).

 

Not sure what you are doing, or why, but even if you paid lift price, you should be able to get 3 for less than $7. Am familiar with this item, as I've purchased this terminal B4. The list price is $2.30 @.

 

yeah well, I just went to a chevy dealership and paid list.

what I was doing was connecting the EST wire on the LTCC harness directly to the PCM. Lot less mess. Just wish I would have been able to do it with the other two wires.
