Alright guys my buddy needs help he has one more wire to hook up he has just the gauge it did not come with the o2 sensor so he dont know what wire to hook up too coming off the o2 sensor any input please help hes trying to hook it up at this moment and dont know shouldnt he connect to the wire thats running to his ecu am i right or wrong someone plz chime in thanks guys

 

so its a narrow band gauge? it need to be tapped into a o2 sensor signal on the ecu, im pretty sure it doesnt go directly to the o2 sensor.... find a diagram for his ecu and find the rear o2 sensor signal

 

Shoulnt it go to the front o2 sensor right or wrong yes its a narrow band gauge

 

i was thinking wideband. it will probbly have to go on the front. but if its catless, the rear should work just as well if not better. a narrowband is more of a light show anyway

 

Thanks man i think he is gonna solder it into pin number 76

 

Mods, please delete or close we have figured it out thanks
