The wiring harness is useful, not necessary, just makes a cleaner easier connection. What you do need is a modulator to process computer codes to your new radio. If you notice, your warning signals come through your factory speakers. The "open door" and "lights on" and "seatbelt" warning chimes come through the radio speakers. Without this little box, you won't get warning chimes. I picked one up at circuit city for about $75. Crutchfield has them too.

| I believe you can swap GM radio. It is easy since they use the same connector/harness. If the radio is Locked, your local dealer can unlock it. Dealer may charge you though. I've heard as high as $150. I ended up buying a standard aftermarket and a mounting kit. I think the GM radio slot is 1 1/2 or double Din. Only other thing is the modulator for the chimes. Most after market radios will sound better than the Delcos. Also the newer radios have the Aux input. Might as well go with new speakers. I swapped out my stock radio from my 03 Z71 for a nice $150 radio. New pioneer speakers for another $150. Ended up selling the Delco radio on Ebay for $175. | |
The radio in my 1990 Sierra acts like the antenna is not hooked up (it's hard to get stations) I looked at the back of the radio and didn't see any conventional antenna wire. I also didn't see anything laying around that looked like an antenna wire. Any ideas?

Replying to: moores (Mar 29, 2008 6:27 am) BTW, the head unit and the receiver/audio amplifier box are two separate boxes for this vehicle. If I am not mistaken, the head unit for this vehicle has the small face with just the radio display and radio buttons. The receiver/amplifier box is a metal box of the size of the brick. It has the antenna connection and the connections to the head unit. You have to search for the receiver box to check the antenna connection (somewhere in the dash ?, just follow the cable harness from the head unit) Before you destroy the dashboard to look for the receiver box, you may want to look at the antenna whip at the front fender to make sure it is still there and have solid connection to the co-ax cable (feeding the receiver box) jt

Replying to: obyone (Apr 13, 2008 3:55 pm) But It would make a person angry to find out after spending hours to undo the dashboard to look at the receiver connection while the problem is somewhere else like the fender whip is missing. jt |
