I just purchased a 21 circuit kit on e-bay for $135.00.The guy had 10 sets and had sold 3 when I bought mine. His name and phone is Andy Cappola, phone# 973-678-6669 . There is a Toll free no. on the box 1-866-462-7628. The name of the harness is Its a Snap. I havent installed it yet but it looks good;and his E-Bay reviews were excellent.
