diagrams are here.
http://www.mymopar.com/index.php?pid=27looks like red for the high beams and dk blue for fuel.
2 different parts of the board.
my best guess is 12 volts is bleeding over from that red line on the circuit board or your vr.
I don't see how, as they seem to be 2 seperate boards.
do you have the low fuel warning light?
as there is a place where the headlight delay and that relay tie in for power. but again, that should be before the vr.
as said above, the only other common thing is ground.
