Never hooked up one but if you post the wiring instructions I'm sure it can't be that hard to do. Someone will help you figure it out.

The gauge will have 3 connections. Power, Ground and signal. The signal wire goes to an O2 sensor. If you use a heated O2 sensor, it may come with 2 white wires and 1 black. The white wires are power and ground, the black is the signal to the gauge.
