Hey Jim,
Check out my previous posts, and if you want those Speed sensors to work, you just need to check the output if you want the computer to actually know the correct speed you are going. The ecu is expecting to see a square wave pulse, with four pulses per revolution of the wheel. The computer considers one pulse to be voltage decreasing to 0V (below 0.1V or something) and increasing to 5V (over 4.7V I think). So if the speed sensor you find outputs a wave you just need to supply it with a ground and 5V from one of the engine sensor power wires and you're all set. Mike Quote:
