I will me mounting some lights soon so what's the best wire to use? I am planing to extend wires from my prerunner bar to the auxiliary wires inside the engine bay.

Also is there any preference on gauge? I assume 12gauge will suffice for this job?

Will these wires work?

Look behind the glove box at the pass through wires the wire that goes to the #1 switch is a 10 gauge wire I think it might be 12 gauge but I use that as a reference for wires I run I use a 12 gauge wire for all my wiring. I have a 20" in my bumper light canons on hood mounts and my rear facing amber dually's all wired with 12 gauge and haven't had any problems so far!

This should help with the wiring as well! What I did was splice all the pass through wires together and labeled them with the corresponding switch so it's easier to hook up anything I need pretty quick!

here, on frf
the 2 main differences in cost of wire are 1) gauge. i have seen some cheap stuff pass as a particular gauge, when it doesnt even look close. we have had customers bring in their amp wire kits that claimed 4 gauge wiring. when we looked at it, it appeared to be 8 gauge wire with 4 gauge insulation. this is a broad spectrum issue. the cheap wire will always have less inside. 2) material. the cheaper wire is aluminum clad copper, meaning the wire is mostly aluminum with a little bit of copper. quality wires will be pure copper, but will include a higher cost.

let me know if you need any wire. we have many different gauge wire here
