check out section, #14 under turbo database, titled "installing an O2 or egt gauge, and why its a good idea.

i think you have a 4 wire o2 sensor, you probably got instructions with the guage, to tap into the signal wire on the O2 i think it is black with a dark green stripe, but read through that, then if you have any more questions just ask.
