Most of the XM units run off of 5v. So cutting the Cig plug off and wiring it to 12v will burn up the XM module. We used to do two different things.....
1. take cig plug apart and solder two wires to the 12v + and -
2. wire a female cig plug to the upfitter switch and plug the male from the XM unit in and tape them together and place behind the dash.
either way will work.
