Wired FM Modulation Relay for Sirius Satellite Radios

Thank you!

spoke with John today - he was very helpful and suggested how i could hook up the power system that i need for portable power - the parts i would need and how I would do it, saves me a LOT of money and (hopefully) will do what i want it to do. He spent lot of time and was very patient - Give this man a raise! S. Hammond
