Aftermarket Mud flap hanger..

You'll need a half inch drill and a good drill bit. Get yourself some 4 pin trailer wiring, a butane torch and solder, some heat shrink tubes, wire cutter, strippers and about 2 hrs.

If this confounds you, you should maybe have someone else do it for you.

I put the same set on my freightliner. It used to have just the two center lights and the reverse light.

 

If the truck originally had 2 taillights that were stop, tail ,turn, just wire them up and they will function the same. If the truck originally had 4 tail lights 2stop 2 turn you will need to rewire the outside lights on the hangers for blinkers.

 

Red wire=Tail light
Green=turn
White=ground

 

If you aren't good with electrical I'd let someone else do it. It's not a hard job at all but if you just hack into the factory harness and don't seal things up good you will have problems later on with wires corroding. Stop and turn signal lights are one wire, clearance or tail lights another and last is ground
