I recently installed a Holley Terminator X on my 1987 Foxbody and lost all gauge cluster function including Battery reference, coolant temp, oil pressure, tach, and fuel level.
I cut the two plugs from my old harness the Grey and Black one i think they're called c110 and I hooked them up as follows.
Gray plug
*******My lights work on the dash including turn signal indicators, headlights, etc.*******
I have no issues on the Holley side my ECU reads RPM just fine and i have no issues starting my car. I'm not sure if i shorted my dash or when i removed the engine harness i removed some sort of common ground for the cluster. If anyone has ran it a similar issue or knows a way for me to test the cluster that would be helpful.
Thanks, Justin

Gray plug
- I have the Green/Yellow and the white tach wire from the Holley TFI pigtail plugged into the negative side of the coil.
- I have the Red/Green plugged into the positive side of the coil.
- I have the Red/White and White/Red hooked up to there designated sensors.
