Where in the hell does the antenna wire plug into on a 1990 chevy k1500 with factory radio, did not see a place on equalizer or radio itself.

BAD CONNECTION? DID YOU PLUG IT BACK IN? OR DAMAGE WIRE? OR PULL OUT FROMM BEHIND DASH

If you have a cigarette lighter check the fuse for it. Usually shared with the radio remote wire.

first of all, is your radio factory or aftermarket? If its factory the you probably have a bad ground or a short in the radio power to antenna. If its after market, then the remote antenna wire is hooked up wrong. Check to make sure the antenna wire is hooked up to the antenna. Good luck

It is grounded to the illumination wire. You need to pull out the radio disconnect the black wire that is coming out of the radio from the adapter plug and bolt it to a good ground.

Best Buy has a pretty good reputation for installing aftermarket radios and they generally use a new harness connected to the old harness to make it work right.

I would try to have the reception issue fixed by Best Buy before the warranty runs out.

How long ago did you have it worked on?

I'm sure they will make it right if you take it back.

Even, if it requires changing out the radio.

Have them check that the antenna is properly connected to the back of the radio.

There are two, if it's 1/4 inch round it goes to the antena if it's a single black wire connected by itself in the middle radio it's the ground and connects to the chassis. All other wires run into the connecter and feed speakers and has the power to it.

i have a 1990 iroc-z and i replaced the radio with an aftermarket radio. when i replaced the factory radio i had to do a little manuvering of the wires because of the alarm i had installed. the antenna wire is supposed to be ran under the PASSENGER side i dont understand why they are under the driver side.

how many miles on the truck? when were the wires last replaced. They may look fine but have very small cracks in them causing interference

Can purchased an adapter kit at Best Buy or Circuit City that is color cordinated with the factory wires for about 12.00. This will go right into the factory plug.
