ok man let me tell you something...
you got fucked.... the reason why your speedometer wasnt working is cuz your speed sensor wasnt pb conected, and your tac pb had a loose wire in the harness.

best thing i would do it talk to taylor durdan from s&r perfomance....
ive heard that martin is good, but i can tell you that taylor will get your shit running the right way garranty. and im talking from a personal experience....
so give them a call....
