I had a few issues with mine as well. Thats the thing with Artic Bomb/DZ motorsports, Rob has awesome customer service and will bend over backwards to get you working properlyI had purchased mine from Arctic Bob and did the same thing, ended up throwing a trans selector code error the second time I took it out. Gave him a call & he sent out another harness - haven't driven it yet but reads like it supposed to. High in low or high gear.
