I think the '94 is behind the glove box or in that vicinity. I forget when they moved them to under the air intake box.

Access to pcm, take off lower kick panel under glove box, remove the 10mm screws holding it in place unplug both connectors, remove.....In 1996 they moved them under airbox.....

Actually, it's one 7mm screw on the right side of the PCM, the left side has a locating pin. And it has 3 connectors. It makes it easier if you remove the glove box also (six T-15 torx screws). I just replaced the chip in my PCM so it's fresh in my mind.

thanks....i'm doing headgaskets\timesert and hopefully i'll be able to feed those three harnesses up through the firewall. after everything that fought me, the only thing stopping me from lowering the cradle was this.

does not have decent bulkhead connector and the access hole is to small to get it through, unless you mangle plug and firewall adding a wind leak....Just pull the wiring off block and on your 94 it is pretty easy..
