hey guys , i have a question, im trying to hook up a narrow band O2 gauge on my 2003 turbo, can i just tap into the O2 sensor (either pre or post cat?) and if so what colour wire would i use?
or do the 03s come with wideband both sides ?

thank

my bad... i wrong, some come with wide bands...
how many wires does the first one have???
the rear once are all narrow bands
...
first one has 5 wires
and none of them are the same colour :icon_eek:

but my tiburon had widebands and they only had 4 wires so who knows.

you think the signal of he back sensor would be good for the AFR gauge ?

my AWM has a wideband O2 sensor pre-cat. on my air/fuel gauge i have 3 wires. i just cant figure out which wire to tap into. I've searched the forums and the net but nothing for a vw. all i can find is for ford/chevy. anyone know?
