A/F gauge install - HELP

[Ruckuss]

Hey guys.

Sorry if this is a stupid question, I just wanted to know what wire I have to tap into for the signal on the O2 sensor.. there are three of them.. not sure what to use... I dont really want to go through the ECU because I was reading on the US boards that some people have had trouble with that route, apparently the guage didn't read anything but when they put it on the sensor it worked...

I tried to search on this but I can't find out what wire is the correct one.

It's the easiest way...just open the hood, locate the O2, pull back the insulation, saulder...done!! 5 minute job

I wired mine directly to the ECU and it works perfectly. I beleive it is to pin #60 if I remember correctly. The only thing that was hard was removing and replacing the metal cover on the ECU... damn that thing is sharp!! http://ib2.toprotege.com/iB_html/non-cgi/emoticons/crazy.gif Make sure you wear a pair of gloves when removing that cover!
