Being an old trlephone man, I hate exposed wires (unsightly), therefore I tried everything to get wires from the taillights down to my trailer hitch. I finally gave up and ran wires down the outside from the lights but hid them in white plastic stick on wiring tracks. Not what I wanted but they don't look too awfully bad.
Amen on the more professional job. I wanted to fish the wall from the lights down but just couldn't manage it. needles to say, I'm not satisfied but sometimes you have to settle. Let me know if you comeup with something better.
They can be accessed from behind the rear tailights. You also MAY be able to access them if you remove part of the underbelly fabric. I know the watertank is back there so finding the wires may be tough.
The wires DO run underneath. On each side. It is a pain in the butt to remove the fabric but it is doable and you'd only have to remove the very rear portion...
I have a stupid question, I know that on my suburban the wires where all ready in a harness and tucked underneith my rear bumper. You might want to take a look at the bottom of your bumper first. They may be through already.
