i just got a STRI auto timer , it also could be use as air fuel ratio display. but it needs to connect to 02 sensor signal from ecu. i dont have any clue where the 02 sensor signal located it.. help?

also if i gonna connect the air fuel ratio, i have to ground it to the ecu ground, where is that ground located ???

i can try and pull a wiring diagram for you

you dont need to ground it to the ecu...but theres two ways to get the signal wire...in the ecu harness or at the o2 sensor in the engine bay...just get a pinout of the ecu harness and locate the wire and tap it

nvm, i cant get a engine performace wiring diagram for any year speed 3

you have a one in 4 shot of guessing lol

two are for the heater and one is signal return and one is sensor ground
