k i have no idea how to install this, its a autometer narrowband gauge im guessing red goes to power black goes to ground and purple goes to the o2 sensor???
Don’t be a ricer.
Didn’t it come with instructions?
red and black should be power, red is always (+) when DC, but make sure in the instructions some companies like to mess their colors up
didnt get instructions

For the wirining. Not sure if you have OBDI or OBDII.
mike you ass, a/f gauges dont make you a ricer, hardparking does… BAHAHA
purple goes to signal, red is power, black is ground, correct.
you dont have to wire to ecu though… just run it to the 02 sensor wiring…
easy shiz, 5 min install
hahaha maybe…
BUT
narrowband a/f = rice
Agreed, wideband is the way to go, :D/
BTW: Mike V-mount setups add the real power right? 
i agree, narrowband does suck, BUT is it not better to have a little idea of whats going on than none at all?
plus, narrowband still has its uses, maybe not for total tuning, but to know how much fuel you are wasting at 3000 in 5th gear crusing when the needle is almost full rich…
ballsface
k and i got these guages for like almost free so it was definitly worth it
