What color wire is Oxygen Sensor?

[CombatComProg]

I'm hooking up an air/fuel gauge and need to know which wire going to the computer is from the oxygen sensor. Also, it says I need to connect the red wire from the gauge to a 5 amp fused and switched 12V positive source that is turned on and off with ignition switch. Where can I find this source? Thanks!

Ign terminal on your fuse box. O2 sensor has a purple wire on it.

Those guages dont work.

But if you like bells''no whistles.. thats ok.

A scanmasterII is whats used by most of us with these cars to monitor O2 voltage. Knock, and other VITAL functions.
