remove passenger knee bolter from the interior look up to the right, kind of hard to see from the inside but if you pop your hood and look underneath the pcm (located at the left of the car) either remove pcm bolts and slide pcm over or do what i did and take a long screw driver, pop off grommet then use a cut up coat hanger or use a screw driver to wrap your wires around then jam through the hole. hope that helps.
looked all over that area yesterday. Removed PCM and slid out the way, and still can't see a damn thing. All I can see is one wire bundle (1" diamenter) down below the PCM. And can't even see it go thru the firewall.
Took off glove box, and noticed an electonic box (looks like the pcm in my 94 silverado) to the right in the glove box. What is that box?

the box behind the glove box is the body control module. ya know, for the airbags and stuff. and with the pcm out from under the hood, the hole is down in the corner (passenger side) where the wires pass through. its pretty big and easy to see. or take out the kick panel and stuff from the inside and look up in the corner that way but removing the pcm is the easiest way to get to it.
