There should be two connectors, they wont interchange.

The one connector is for the sensor, its a complete harness, so you shouldnt need any connection ifnormation there. If its cut, match up the wires ;)

There should be 4 wires off the other connector

Red - Goes to 12V + fused
Black - Goes to good ground
White - this is the 0-5 VDC output, I use this to data log via my SSI-4
Blue - This is the serial output, if he is going to use this, he will need more information.

Basically to use it as a gauge, +12V to the red, Ground the black, and plug in the sensor harness :D
