Some tips on C4 Receiver module removal (coupe, 90-93):
These instructions came to me via IM from Shoregasm, thanks! I did some minor editing and such.... but the bulk of this comes from Shoregasm.
1. Remove the air vents under the glove box.
2. Unscrew the underneath cover below the kneepad carpet under the glove box. Pull the carpet corner under the fuse box. It's sort of a press fit. Bend it back.
3. The receiver box which has the antenna lead is silver. The plugs face the fuse box. Two clips top and bottom hold them in two separate harness' come out as one.
4. GM harness is a standard item. You only need the power related one. It includes the power antenna lead, ignition lead, Ground and Battery lead - all in the same harness.
I used the GM harness and then added about 1 1/2 foot of extra wire and ran it under the kneepad carpet and in a hole large enough for the entire aftermarket Sony HU harness (most harnesses are about the same size). Plenty of room in there.
5. Using a long screwdriver, pop out the antenna lead from the silver receiver box. There is one clip in plain site that needs to be popped loose. There is a screw mount holding it closer to the dash. No way to get that one. A short antenna extension and GM adapter will give plenty of reach to the new HU. Done.
If you have a new HU that takes RCA's that plug into the back of it then you will need to trim a piece behind the dash. It will prevent the deck form sliding all the way in. Drill bit will cut a nice fast notch on the right middle side of the plastic. There is a YELLOW box that has a clip. Just pop that off and tuck out of the way. Some head units will have leads that make the actual connection of the RCA's remote from the head unit.
As an aside, a very important aside, anything in the dash that is yellow is related to the airbag. Be VERY careful not to cut, splice, or spindle those wires.
Hope that is what you were looking for....
