I am installing a speedometer on a 97 scrambler 400 4x4. The kit is for a 99 Scrambler 400 4x4. I am just wondering if anyone has the wiring diagram for a 99. I also want to know how the sensor works. The instructions that came with it say mount it on the front right caliper. I can't get the needle to move. I have the wires hooked up (Not 100% sure if its right) and I do have power. The lihgt works, and the memory works. Any suggestions or comments would be greatly appreciated.
