I have an aftermarket chip in my diesel truck. A shielded cable connects to a digital interface to change the power levels. Problem is that I am getting radio interference from it, it is a known problem. Weak signals get a lot of static. Unfortunately the station I like is a little weak.

Does anyone know where I can get some shielded tubing? I would rather not use aluminum foil.

 

Thanks for your help.

I look forward to your responses.

The two that come to my mind are either Radio Shack or Fry's Electronics.

 

You could also try a local audio install shop.

I'll give it a shot tonight

 

Thanks
