I was going to replace the ECM and i found a plug that went nowhere

it had 3 wires, a green,grey and a black wire

on the plug it said A B C

what and the hell is that plug for????

Fly: is the plug a part of the engine harness or the dash harness. I have a copy of the Packard Electric engine wiring harness print for our cars, and will dig it out and see if it shows that connector on it. I seem to remember one "hanging" in the area of my ECM when I replaced the engine harness, but don't remember if it was on the engine, or, dash side.Let me know if it's on the engine side and I will let you know what it is. turbota.
