get a pen tester. 3 of the wires are for the o2 heater. if i had to pick i'd say the blue wire. cause there's 1 5v 2 ground and 1 signal wire

the white wire on the front of the engine is the one to tap for simplicity i tapped the one in the middle of my car which is alot harder to get to

Success!! Finally got the air/fuel gauge to work. I just tapped into the blue wire and turned on the car and waited for a couple minutes. I see no purpose for it really, but I got it working (w/ the help of some of you here). I dont see how its suppose to be accurate at all. All it does is go back and forth. Only when you go WOT, shows a steady reading, but other then that its just for show. (your right Yanks:D )
So people with a 2000 solara, you must spend a crap load of money to get an accurate reading.:rolleyes:
