Thanks for all your replies. They were most helpful. I needed that information in order to wire my Roadtech XM radio to the accessory plug. I wanted to test it out without using the ignition switch which primes the fuel pump. After some initial wiring and testing with the ACC switched on, I was able to pull the fuel tank without pulling fuses and such, in order to run the wires in the channel on the frame. Eveything works great now.

Thanks again,
John
