What powers the computer??
I am going through my harness (from a 2000 Camaro) and deleting everything not needed (hybrid), but wondering what wire or sensor does the computer get its power from?
Does anyone have a wiring schematic of the harness?
Any help is greatly appreciated.
O.K., now my new question: I need plug # 19 (ign positive voltage), 20 (Batt positive voltage) and 57 (Batt positive voltage) on the blue plug. Since I dont have the other end of the plug or know where it goes, can I just run these three wires as they seem to the battery and to the ignition? Thanks

edit: doh ya beat me to it the link above is from that very same post
also note for most purposes 99-02 PCMs can be treated the same (I'm running a 2002 PCM w/flash on my 2000 car)

sounds like it... but I'm not 100% sure , hopefully some of the hybrid/transplant guys will step in.
Regarding flashing the PCM , you have a few options
I flashed mine using HP Tuners (I had a 2000 and 2002 license at the time, now have all V8 F-Body licenses) The other option is to have a dealership do it... but they'll need it in a car (since they flash via the OBDII port just as the other software packages do)
One option is to post in the western section and see if there's anyone close by w/HP Tuners for a 99 and 2002 (2 license on 1 cable) and see if you can set something up to have them flash it in their car.
Realistically though... unless you have some tuning software.. i'd leave the 99 PCM in it (if the motor's a 99)
Since 99 and 00 had a different cam and LS1 intake manifold, the tune is slightly different (also timing is more aggressive)
I flashed to a 2002 PCM OS because I run speed density (no MAF) and the 2001+ F-Body PCMs don't have a secondary VE table that needs tweaking... however if you don't have a means to tune the PCM then the 99 OS will probably be a better solution

Sandking and I are building the same off road truck.So emissions are not an issue.We are running a th-400 trans.My question is,What is the minimum sensors and wiring we need to have to make the motor run? We want to trim off everything that is not needed. Thanks in advance.

Sandking:
I have a 99 factory service manual so I can check the connections when I get home tonight, if you don't get an answer.
Horist, I want to do the same thing, go MAFless and get rid of the secondary table. I pieced the engine together, and it isn't stock, so I have no problem with that. I was wondering if it was possible to get a license to 99 and 2001 (or 2) and do it with HP Tuners. Good to know. Thanks.
