I was reassembling the Dodge and decided to pull back the floor liner on the driver side.

Should I have a pile of wires there? Just seems like I have about 15 too many wires running around..

There is a 1/4 inch round cable (looks like coax) and some smaller wires.

 

I think those are for your dome lights, cab mounted brake light, overhead cab clearance lights, and if you have one of those computer things that tell you the temp above your rear view mirror.

 

There just seems to be a bunch. I will be pulling the seat and floor covering later this summer and hopefully will straighten the mess out. After looking under the dash this week I am kind of amazed ANYTHING works on the truck...
