i just picked up a boost/vacume gauge and a air/fuel gauge, they are autometer phantoms and in perfect working order, brand new.

but i need to know how to hook up the a/f gauges, where do the wires hook to. thanks for any help, i know how to hook up the boost gauge.

 

There should be a black ground.. a red ignition source wire.. and then a purple? or other colored wire that you need to get an inline splice for and hook it directly into the feed from O2 sensor..

An important thing to remember with the O2 sensor is that they are a little sporadic in their readings due to the flow of exhaust over the sensor.. when you have it powered up you will see what I mean..

 

ya i know about that, my brother has one and ive seen them before, i think they are cool as hell, i guess i dont really need it that much but oh well. thanks for the info, you were right on the coloring of the wireing too.

sweet car be the way.
