From what I've read, do check all of your grounds to make sure they're tight. If you still can't get rid of the noise, you might want to install a noise filter in-line with your power going to your radio/intercom/cb. They're in-expensive and reasonbly easy to install.

But, I'd wait and see who else weighs in on this subject as they may have a better fix for you. Still, while you're waiting, check your grounds.

Regards,

My problem with the advice that I'm going to give you is that I'm not familiar with the 1500 wiring harness. You might want to enlist the help of a local stereo/electronics store that has technicians working in house.

I put an in-line filter to my cheap intercom and it cleared up all of the noise that I was getting(spark & alternator) But, I knew which wire was what to the intercom. So, if you've got someone who's knowledgeableabout your wiring, it would help immensely.

Sorry I can't be more specific, but I don't want to give you bad advice. Keep checking this board and maybe someone will pop in with the info. you need.
