II have a check engine light on and I hooked up my scanner to read the error code. The problem is the scanner does not power up so I checked between pins 16 (+V) and pin 4 (GND) and got no voltage reading on the vehicle connector. I tried the scanner in another vehicle and it works. DoEs anyone know where the voltage originates from?
Thanks

Any chance I could get those schematics? Building a wire harness and I need to figure out how to wire in the DLC.
