sat radio pin guide?

[VQ]

Anyone know where I can find a guide showing what the dozen or so pins on the sat wiring harness/connector do? I'd like to see if there's a way to have both XM and Sirius wired into the system, and switch between the two via a relay or switch.

Basically, they would both need to remain powered at all times, but then the relay would switch over the bus and audio connections.

Any ideas?

Yeah, I thought about that too. What I was thinking, although I haven't thought all this completely out yet, is to some how get another plug or better yet make a splitter with two heads that the trunk connection would plug into. Plug the both of them into the units at the same time, first find the power line using a tester, then using a multi gang switch cut all the the rest of the wires and connect them up to the switch. So what you will need is a 2 position switch, on/on with several leads in and several leads out of each position. I did the same thing when I modded my playstation. I bought the switch here locally at a electronics speciality shop.

Now I wonder where the SAT prest channel information is stored? I'm thinking it is in the Sat radio unit, so you might be able to have presets for both XM and Sirius. The only reason I say that is when I switched my XM units (1st one defective)I had to re-ented all the presets.
