the auto meter they have black, red ,white and green , the black is the earth, red is the power supply 12v, white is for the light of the tacho and green needs to be connected to the ecu Ignition feedback from the ignitor - coil plus is more easyer you need to splice the wire a bit and connected there hope that helps
