You will need a lot of various gauge wire.
Match the wire gauge you're extending.
It's really not THAT many wires.
Label both sides before you cut wires and it will be fairly easy.

alright yea im just going to extend my headlights ,turn signals,wiper motor my battery is already relocated in the trunk with 0 gauge

Also probably have to extend BMC plug, Alternator wiring, lower harness plugs

I have a pro series ws harness it's built in so no need on extending for that

you're going to have multiple wire sizes.

you should also solder and shrink tube them as opposed to butt splicing (if that's what you were going to do)

Yes just bought shrink tube I told my buddy whose comeing to help after I read more on it and he said me extending my headlights turn signals and the 2 plugs on fuse box he said it's not as easy as it sounds there's more to it do I have to shorten anything ? And when I extend will that change resistance then I have to put a bigger fuse ?

[KAT-PWR]

No it'll work fine. Whether you shorten the harness or not will depend a lot on how much time you spend routing it. I shortened nothing and managed to tuck everything pretty good. Leaving enough slack that dropping the glove box it'll sit comfortably on the carpet with no stress on the wires.
