I got a Air Fuel Ratio gauge and it says splice into the grey wire on the o2 sensor but where is it? on the UP, DP, or what?



also I got 2 other gauges hooked up and they work, except for lighting theres a red for power (obiovusly) and a orange for ignition, where do i hook up the red+orange.

I did the fog light mod so i was just gonna tie them into my DRLs, maybe?

The tap-in type A/F gauges can ONLY be connected to the rear 02 sensor, never the front. They can only read the signal from a narrowband sensor. As such any readings on that gauge will be worthless, and this is well-documented in many threads here.
You should only bother to install that gauge if you don't mind that it will not display any useful information.

ok, thats cool


my other questions?
