I have a 2003 explorer that I am installing a trailer brake and constant power lead. I need to run a two lead wire from the back to the engine compartment. My question is where can I run the wire without getting too close to the rear suspension parts that move and the muffler? From the rear wheels forward is the easy part.

 

Just zip tie it to a existing wiring harness. They are already routed in a safe place

 

Thanks for the reply. The rear wiring was a piece of cake. I figured the routing for the 2 conductor wire to the engine compartment.. I had to remove the rear wheel which made it easy to run it through part of the frame, avoiding any moving suspension parts.
