What all is involved when removing the PCM and the engine wiring harness??? I have my engine/tranny out of the car and I want to remove the PCM and harness out of the way to make it easier to clean things up, wiring other things easier, and make life simpler. Thanks

I'm pretty sure the pcm is that grey box under the hood, against the firewall on the passenger side2000 silver A4 Camaro<br />Whisper lid; Free Ram Air; BMR stb; MSD super conductor wires; Gatorback belt?<br />1986 RX-7 (daily driver)Comment

To remove the PCM, remove the two screws holding the two plugs into the PCM. One is clear plastic and one is blue. As you unscrew the little bolts, the plugs will come out. Once the bolts are loose, gently pull on the plugs and they will come off. Move them to the side. The PCM is held in its bracket by two clips, one on each side. Hold those clips out and pull the PCM out. I find it easier if i remove the two bolts holding the bracket so I can move the bracket around to get more clearance. When re-installing, make sure the bracket is in the little slot in the fender and do not over tighten the screws thst hold the plugs in the PCM.
You are on your own for the rest of the harness. It should be just a matter of finding all the little clips and plugs.
