Can't get AM stations to come in very well on my 88 suburban square body. It has an aftermarket antenna mounted in the original location that comes from the inner part of the fender and goes under the hood into the firewall and then into the stereo it's not one solid piece its two pieces going up and over the heater controls which I'm sure is causing interference. So I'm curious does anybody know where the factory cable is supposed to be routed and where I could get the factory antenna with one solid connection all the way to the stereo? any help would be appreciated thank you. I've tried searching for this for quite a while and I have had no luck. If this truck was equipped with the windshield antenna it's been long gone the windshield has been replaced. But any info where I could reroute a new cable to cut out any interference would be helpful thank you.
