hate the sweep gauge... had to change it. i know wires had to be rearranged.. so i rearranged them and ended up with two extras; an extra black and an extra light blue. also, there are an extra two wires missing from the stock plug, and i dunno where they come from... but after i plugged it all in, the oil gauge bounced a bit then just went back to its original location, nothing else moves... why is this?
