I want to add a REC radio to my Jeep, but hit a problem. My Jeep is the base Laredo with the RAQ radio. I put my REC radio in, but it would never turn on. I read that the CAN BUS sends the signal to turn the radio on. When I looked at the wiring plug going to the radio, there are no CAN BUS wires going to the radio. Where do I get the CAN BUS B wire connections from to add the wires to my REC radio?
