There is a good thread on installing the wilson switch, find the wire to the solenoid that feeds 12 volts, not the one with resister in line to drop volotage.
Just did one, all my wiring was done under the dash, as apposed to the way I use to do it from in cab into engine bay.
Hey aren't Cdn BJ70's 12V?
