Ok, in the for dummies post, the PCM pinout was posted. Now, the problem I have is this. There are 2 PCM bat connections which seems a little odd to me, why would this not be an internal connection? And second there are B30 pnk PCM Ignition Feed D30 pnk PCM Ignition Feed, and I wonder are these ignition feeds as in the ignition system that creates spark, or some people call the cranking switch the ignition switch (maybe just old timers, I dunno...) but I thought maybe this is the switched power for the PCM. Doesn't the PCM have some sort of switched power? When I turn the key, I do not get power on the fuel pump enable line which is what I was working on when I went back for the information and found the 2 bat connections, and 2 ign feed lines... Thanks for the clarification Corry

B15 & B31 should have constant power(B+).

D3(pnk) & B30(pnk) should be connected to a switched ignition source.

I believe that that D3 ties into B30 leaving only the end of B30 to be connected.

B30 eventually ties into the fuel pump enable relay and the theft deterrant module. I'm betting as long as everything else is connected properly, connecting the pink B30 to a switched ignition source(maybe at the column) would get your pump to cycle.

Can any one help i have a 96 ta with a lt1 in it and in need to find out which wire is my signal wire on my 02 sensor it has 4 wires So its a heated O2 it has a white a purple and two Brown/tan (whatever color you wana call um) I thing the white wire is the signal the purple is the reference volt. and two Brown/tan (whatever color you wana call um) control the O2s heating but i dont know and i dont want to mess up my baby so any help would be greatly appricated.
