On the ECU harness, there is a white wire with a single blade connector, mine is missing the male end in the harness, does anyone know what this wire is for? Also, what could it affect if it is unplugged?

Re: ECM wiring issue
Per Mr. DaveP:
"That wire is the Mystery Wire. It is only found in a 93. It is part of the cruise
control harness. Beginning in 93 there is an input from the cruise to the ecm to modify
TCC and shift schedules of the 4L60e to enhance throttle control when cruise is engaged.
Because the Typhoon does not use the 60e transmission, or the harness that has the
mating connector, the wire is just left hangine (disconnected) in the Typhoon. Leave it
disconnected. That's the way it's been for 20 years".
