Someone added turn indicators to the truck and installed 2 extra lamps to make it work. I am going to remove the added lamps install a rt. tail lamp like the lt. one and install a 3 to 2 trailer wiring adaptor. (normaly used on a vehicle with separate turn and brake lamps.) Do any of you see a problem with this?
