I used this for my old 10,000 winch and it work perfect.. I put it under the hood which was better then putting on the winch like the company did.. I tried to put it back the same, darn near got it. But then I looked at myself and said hey fool you would have been done sooner if you would just put it under the hood. I did . So sweet. the extra cable they gave helped me out big time.
