I'm hooking up my pyrometer and need to know an easy, convenient place to tap in for the + wire on gauge light. Any ideas? Thanks.

 

If I remember right it is the orange wire with the white stripe coming off the back of the headlight switch harness. Somebody just had a post on this with pictures, try a search for light wire.
On edit: it was member: Sailpipes, check his photos.

 

Thanks! I found it. I just probed the wires with my ohm meter until I found the right one. Once again, this site proves to be a major asset to us Dodge owners! Good job, everyone!
