...if i did install one myself, will the wires need to be spliced and cut, or does everything just plug into a wire harnesses?

 

No strait plug in. Has to be spliced into existing wiring in the truck.

 

thank-you

 

read your post just want to make sure you do not cut wires on truck strip insulation and wrap and solder wires then tape with a good quallity tape like 3m temflex about a $1 a roll but worth the extra 50 cents. Take your time and ask questions if unsure. Use multi meter and verify all circuits before you tie into them. I can't stress enough to use multi meter unless you have done this before and now how to test and when to use test light you can damage very expensive components with test light. If you have any questions msg me and i will try and help
