No, you are pretty much literally "slapping on the winch and plugging in the wires", or at least that's how mine is going so far. It was complete and working when it was taken off the truck, and the seller included all the parts. Even the non-winch trucks have all the wiring and mounting holes already. The setup is fairly simple too... the winch connects to the PTO with a couple hoses, and the PTO connects to the reservoir tank, so it's a fairly self-contained setup, that doesn't really involve much integration or comingling with anything on the truck. The one thing that is a swap is the front passenger cab mount bracket with this new one off the winch truck, because the winch truck's mount bracket has a roller on it for the cable, but it doesn't look like anything else has to come off to replace that bracket (and the seller said as much, but I still checked for myself).
So there is no "project" in the sense of anything to create, figure out, fabricate, etc. Now, if you're trying to cobble something together from surplus/parts/etc., that would be a different story, sure. With the electric winches you still have to take the front (and rear?) bumper apart and design and fabricate those mounts, which are a couple weekends projects in their own too.
