Been working out of town the last month, but have gotten a few things going the right direction now. Found a few places to buy Delphi connector parts, including the pins, back shells, and colored covers for the ECU connectors. I was thinking of using the camaro forward harness assembly I have but there is a LOT of it that would be wrong/too long/too short, so I am going to split it and make an "engine" harness, "engine bay" harness, a "transmission" harness, and a "body" harness.

The trans harness will be for the manual, but the EFI harness that it plugs into would have all the auto trans stuff populated. This way if I keep breaking T5's I can just plug in the 4l75e I have sitting in my floor. I haven't converted the bellhousing yet, I am still thinking about that.

Did the 4l60e's with removable bells ever come behind the V660? I haven't seen one yet.
