Rev,
approximately where on the firewall. I find your comment interesting since I've had a couple other odd electrical gremlins that tend to come and go. be worth me checking out while I'm at it.

Thanks

 

Ok, I finally got a chance to check the voltages and this seems a little odd to me. I show 11.5v with or without the switch pressed.
Maybe I'm wrong, but I would have expected no voltage until the switch was pressed and then to see around 12v come across when activated.

Anyone have insight?

 

Still haven't figured this out.
Anyone have any thoughts for me?

 

if I have some time tonight I'll yank mine off and check.

 

I have a 06 durango with the 5.7 with the same problem. I tested the harness and I get no volts at all. Been looking for the fuse and no one has a clue.
