Follow the directions and read the wiring diagrams for your car.

the autometer air fuel ratio gauge has 3 cables a blue one a red one and a blck one. I installed it like this...

blue: extend a wire all the way until the Oxigen sensor cable ( your oxigen sensor must be in the down pipe.

Black: I connected it directly in to the negative end of the battery for a better ground.

Red: I tapped in to the cigarrete light on the fuse box

it works like a charm.
