It is on a rupp roadser, On a rupp wiring harness it has to hot circuits and a gruond for the kill switch. most snowblowers have a 5 amp ac circuit and 3 amp dc circuit. I made both circuits ac, wired them into the stock harness. and the ground for the kill also goes right into the harness. One circuit runs the head and tail light, the other is for the brake light! If you have any spare snow blower motors laying around let me know i would like to build another!:laugh: Good luck, any questions feel free to ask mat
