sorry thats air to fuel

 

If they are AutoMeter gauges, they came with instructions, or you can pick up the instructions online at the AutoMeter website.

The A/F ratio gauge needs to have the purple wire connected to the signal wire for one of your O2 sensors. Splice into the wiring harness, not the sensor wires. There is a purple signal wire for one bank of the engine, and a purple/white signal wire for the other side, and they connect to pins C8 and C20 in the gray PCM connector. To be able to read both sides, one at a time, pick up both signal wires, run them to opposite sides of a single-pole/double-throw (SPDT) switch and you can select whether to dislpay the left or right bank sensor. When you get all done, you will have a cute little (actually quite annoying) psychedelic light show for normal driving, and the gauge will indicate "rich" at WOT. Its not providing a lot of useful info, unless it tells you the sensor failed.

The vacuum gauge needs to be connected to any "full vacuum" port on the intake manifold. Choose from the ones for the EGR solenoid, HVAC controls or fuel pressure regulator vacuum compensation line. Shoebox has pictures of each of those connections on his very help Tech Pages website.

 

thanks for the help, do you have shoebox's link?
