My understanding, and how it was explained to me by a forum member here when I bought my '81, is that if you ditch the factory carb you can ditch the computer. The only thing the computer does is control the Air/fuel mixture through the carb. basically it takes readings off of 4 sensors on the engine and uses that data to keep the air/fuel mixture a specific percentage... for some reason 14.8% is popping into my head but I'm sure I'm probably wrong on that... It's been a few years since I looked into it. I decided a long time ago that if the computer ever dies on me I'm just going to put an edlebrock 650cfm on it and get rid of the computer all together... lol

The ccc controls the dist , carb and the lock up torque converter. You will also lose the power to the ac presure switch if the harness is removed. I think power is jumpered off a relay that feeds the egr valve

What about the console area, there was a connector located in the shift lever area think it was a single brown wire, there were others but determined they were scanner port wires..
