I just bougth a air fuel gauge and a volt gauge.Can someone let me know how to install them thanks

didnt they come with instructions?

Normally Im guessing the volt will have 3 wires, 1 goes to positive of battery 1 goes to negative of battery, 1 goes to something that turns on when you turn on the car, so like the dimmer wire or your headlight signal. Some people also hook this up to the remote wire of a cd player, (note it will only lite up when you have ur cd player on)


a/f - one goes to 12v power one goes to ground one to same switched like above, and then the other should go to the purple wire from the 02 sensor on the exhaust manifold.

You can also trace that wire back to the ecu and splice it there for easier access.
