got air/fuel guage, what wire to hook up, how to make switch???

[spunger]

Well I got my digital air/fuel guage today. I got 3 wires, one power, one ground, and one to hook up to the sensor.

My question is:

1. What wire do I hook the air/fuel guage up to?

2. How can I make a switch to switch between each sensor? So I can monitor left bank and right bank?


Please let me know,
Chris

red goes to power
black goes to ground
purple or whatever color it is goes into your engine, follow the wire from the o2 sensor on your header/manifold up to the pcm, splice into it with this one, solder if possible, and use some electrical tape.
If you want to view on a switch, run another wire to the other plug, and run both of those on a switch
or, if you have a 3.8L, you can have an o2 bung welded before the cat and have it run there w/o needing a switch.

Thanks v6maro. I am curious though, so you need to go all the way back to the PCM, or can you just tap though the drivers side O2 sensor and use it from there?

Also, wouldn't you need a special switch to be able to switch between the 2 sensors? You can't monitor both of them at the same time can you?

Just curious,
Chris
