I am trying to install a 5.0 in a 88 that used to have a 2.3 in it and can't seem to find a complete diagram of what all the wire at the EEC are for. The donor car is a 86 cougar. I have the basic engine wiring figured but can't seem to find out what the rest of the wiring is for. I know some was for the AC and have eliminated that but am stuck on the other circuits. The donor car had every option available in 86 and all the cavities are full in the EEC. Can anyone help with a diagram.
