HELP! Air/Fuel Ratio Gauge
I need help installing my A/F Gauge (Autometer)... Where do I hook the power cable to the ignition switch, there's soooo many wires. Also, should I wire it to the ECU or the O2 sensor... Help!

black - ground
red - power - any 12V that is on when the car is on. ie, Radio fuse, remote wire, etc...
purple - White wire on the O2 sensor - DO NOT GROUND OUT!

I hook my power wire to a 20A fuse inside the car, the ground wire to the ground wire on my dimmer switch for my dash lights and the purple wire to the white wire on the first o2 sensor....

Anyone? I installed it but it doesn't like like it's functioning properly. 
The band is supposed to go back and forth at idle, mine doesn't... it stays in one place.

Re: (93preludeh22)
i have a bosch O2 Sensor with the same wire colors, hook it to the GRAY wire. the two white ones are for the O2 heater, gray is the signal, and black is the ground for the signal.

My car is OBD1, I hooked it up to the grey wire, nothing is happening! When it was hooked up to one of the white wires, I was getting stuff on the air/fuel gauge.
