Computer problem
1988 Ford F250 V8 Two Wheel Drive Automatic

there is no single wire lead coming out of the computer that is supposed to hook up to current testers. Have taken all the wires loose and followed them. The single lead is not on the vehicle. Colors followed, red, green and white/red. This is an early 88 with 460, is there another way of testing and reseting the sensors.

just disconnect the battery if you want to reset everything.
