95cobraguy gave you the location its a pain to remove and reinstall with the chip installed. be sure to secure chip in top plug and secure with tape tightly around computer and chip but not too tape much where it will cause overheating. i used black electrical tape.
Thanks...I knew where there computer was, I knew where the chip plugs in, but now its about getting it out. My only question now is, what exactly unplugs from the bottom. I am looking at mine, and the bottom has wires going into it with a black plastic cap covering it. Does the whole light grey thing on the bottom unplug from the metal part?....lol...if you can even understand what I am saying. It just seems like the bottom has to unplug for it to come out.
what your talking about is the main connector going into the computer, u dont have to disconnect that to get it out. if your going to unplug it or if your plugging in a chip or anyhting like that i would disconnect the battery first.
There is one main connector (it's a 60pin if I remember right), that plugs directly into the PCM. This may or may not have to be removed. I had to remove mine to get the PCM out. No biggie, just one bolt that holds it in. There are 3 other plugs/harnesses that run directly in front of the PCM (you'll see them when you take the kick panel off), the middle one will need to be unplugged, the two outer ones can be moved out of the way, and the PCM should slide out between them. Once the chip is installed, the PCM will probably NOT fit back in where that plastic bracket is. Simply break the bracket off (much easier than unbolting it) and it should fit back in.
EDIT: I forgot the most important part. ANYTIME you are working with the PCM, unhook the battery and turn on your headlight switch, and let the car sit for AT LEAST 10-15 minutes!! This will drain any residual power in the electrical system, preventing your PCM from getting fried when unplugging/plugging in the connections.
Oh yea, make sure to clean that J3 port EXTREMELY WELL!! Rubbing alcohol and a pencil eraser works really well.
