Step 11

Route the 4-flat up to the rear of the front 

tire. From the engine compartment under the 

hood, on the driver's side, run a fishwire down 

between the inner and outer fender. The wire 

will come out at the back of the front tire.

Step 12

Route the wire between the body and the 

engine mount. Attach to the fishwire and pull 

the 4-flat up into the engine compartment. 

Route the 4-flat along the driver side front 

fender to an accessible mounting location 

in front of the vehicle.

Step 10

Route the 4-flat of the RV harness from the 

rear of the vehicle, over the top of the rear 

drive-line suspension, along the body frame 

to the back of the front tire. Use zip ties to 

secure the harness in place.

Do not tighten, allowing for later adjustment. 

Step 13

Pull all of the excess wire so that it is not loose. Do not pull it too tight, this can cause unnecessary strain on 

the wire and could cause a breakage over time. After removing all slack from the 4-flat wire, tighten any cable 

ties and add as needed. Use a cable tie to fasten any excess wire to a solid spot along the driver's side inner fender.

Reinstall all items removed during install. If it was disconnected at the beginning of the installation, 

reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion.
