I have a 85ea82 turbo, Just wondering there's 3 wires coming off my disty 2 go to the coil pos and neg but the third has a plug on it and has never been plugged into anything since i've had the car. Just wondering because does seem to be running as strong as my last motor, runs good but the boost power seems very weak. Also seems to be knocking fairly often from just reving it up. any help would be great Jay

There should be 4 wires coming out of the dizzy. 2 to the coil, and the other 2 are for the Knock system control unit. Open up the cap, there should be 4 prongs that the wires hook to on the pickup, on the plate under the rotor, you'll see at least those 3 going to it, sounds like one is altogether missing.
