Just got my Viper winch yesterday and it come w/ all the wiring you will need. I have not installed yet, but did read all the instructions and am somewhat familiar w/ wiring. You will run a heavy gauge wire (pos and neg) direct from the battery to the contactor which will mount somewhere under the hood. ANother set of heavy gauge wire runs from the contactor to the actual winch. The light gauge wires from the dash/ remote switch can use exisiting wiring under the hood--specifically at the terminal block. You will tap into the chassis ground as well as the "keyed hot" on this block. To answer your question in part....there are no existing heavy gauge wires up front under the hood to tap into.
