I was reading the box of my knight hauler and it said that the switch in the turntable gave it more power which i had never noticed it with the trailer so i went and got a two way toggle switch and wired it up to the black and green wires. so now ive got more power with or without a trailer. I mounted it under the back of the sleeper so it is hidden, I have put two small LED's in the air intakes on either side of the bonnet and put the rear plate and mud flaps on and I also made aerials out of mig wire and wire connectors hope you guys like it
