You can use an add-a-fuse to get power from the primary fuse box under the hood. Find one with the same amperage as the donor vehicle and verify that it has ignition only power. Otherwise, your lights won't go off with the ignition. You would also need a relay and aftermarket switch unless you can transplant the original harness which probably has the relay. I have aftermarket fogs in addition to the factory ones, so I added a toggle switch in the vacant cubby area where some models have the 4-wheel drive controls. Mine is 2WD so there just an open compartment. I made an aluminum backing plate and spray painted it to match the pewter interior. You'd think it was a factory switch by looking at it. Of course my new lights came with the harness and relay.
