That grey plug is tach signal to cluster and the power for the coil.

BLUE needs 12v switched (12v ONLY with key ON) and then the RED/WHITE goes to your tach.

Connect that blue wire to whichever wire powers your coil.

If you want to run a tach, you run that red/white wire to the back of the cluster and plug it in!

NOTE: When pulling a harness from a donor car, don't be a noob and cut the wires right at the plug! Cut AT LEAST 6 inches after the plug so you have the connectors and a pigtail lead.
