Does anybody have any clue what wires connect where? I bought the AEM uego wideband gauge by itself. Then ordered the uego o2 sensor for it to put on exhaust. I bought it from prostreetonline and it came with no instructions. All it has is the gauge with 2 wire harnesses coming out the back with the end of them spliced and ready to be connected, but I have no idea where to. I've searched over and over again but no luck. Maybe I have over looked something. Any help?????

/\/\/\ what he said... i also have the uego a/f gauge without instructions...

DSM- Developing Smarter Mechanics since 1990

From the back of the UEGO Gauge, with partnumber 10-4000, 30-4111,4112,4121, and 4211:

Red: 12V Power
Black: Chasis Ground
White: 0-5v output for standalone input
Blue: Serial Output

The rest goto the Bosch Laser calibrated O2 sensor...

I have the 30-4213
