well now with only one small lead on the gpr,which is the power lead,with the key on both terminals are getting 12v somehow.
ok theres two small wires connected to the gpr,one is power with key on,other pcm grounds,then its energized.i left the ground wire untouched,took the power lead off of the gpr,routed to a switch inside the cab.from the switch i brought it back out to a relay.goes in the relay then comes back out to the gpr.after all of this,im getting 12v to both terminals,even if only one small wire is hooked up.
