Hey guys, I have an 03 Ram with the stock head unit, no infinity system or cd changer. It's the standard radio/single cd player (no cassette either). I will be getting a Sirius plug and play unit soon (sportster 5) and was checking out the FM relay. With this you plug your stock antenna wire into the relay, and the relay plugs into the head unit, but I've heard it doesn't work with the older Chrysler radios.

The only other part that I could find that should work is an auxiliary adaptor but it runs about $70 (http://www.tss-radio.com/connect-aud...56_257_53.html). Is there anyway I can buy the Sirius relay and splice some wires somehow?
