my winch came with a "fixed" positive 2/0 gauge wire coming out of it. I plan on adding a quick connect in its place so that i can move the winch from front to rear of my truck when i need to. I had planned on using 4/0 wire to run to the rear to accomodate voltage drop. My question is, what good would it to since i'd be cutting the stock 2/0 wire to put the quick connect and 4/0 on it? Would this small piece of 2/0 negate the 4/0 i'm using and heat up too quickly? i havent take the winch solenoid apart but i might be able to wire in the 4/0 all the way. The truck and winch folks told me to cut the wire, but it doesnt make much sense if i'm adding a thicker gauge in the mix.
my next question is on the ground cable. Does this have to be the same or greater gauge than the positive wire?
I will likely be grounding to the frame in the rear of the truck, then beefing the ground from the battery to the frame so i can ground it to the frame in the front as well.. not sure yet, might just ground directly to battery up front.
