Some vehicles built in 1994 and 1995 are actually OBD-I vehicles but have an OBD-II Connector. Please use the wiring diagram below to see how you can use the GM ALDL OBD-I cable 20110 to connect to these vehicles.

We suggest you use two jumper cables. One end with an alligator clip and one end attached to a male pin. Attach the alligator clip end to the pin on the AutoXray cable - insert the pin end of the jumper cable into the female socket on your vehicle's connector.
