Air/Fuel Gauge Hookup...

With the oxygen sencor, which wire would i want to hook the air/fuel ratio gauge wire up to for it to read correctly? i believe there are 2 green, white, gray but im not positive... does snyone know which wire i would splice into or should i just go straight for an ecu hookup?

If you also had any suggestions for which vacuume line to tap a vacuume gauge into that would be helpful also... i was thinking the one off the throttle body because the hose is a bit worn and needs to be replaced... would that be a good choice?

thanks for any input, have a good xmas.

Tap into your 02 sensor wire at the ECU. 2gnt has ECU pinouts for the ecu so check those out and that will tell you where the wire is. For the vac gauge anything on the intake manifold should work. You should be pulling 17-19 in.hg at idle so as long as your getting that you will be fine.

sounds good thanks
