autometer air fuel

ok i have a question i wanna hook up my af gauge under the hood but in my haynes manual in the electrical it has 4 options..... heated o2 bank1 sensor 1 " " bank1 sensor2 , " " bank2 sensor1 , bank2 sensor2 what do these relate to... is bank 1 the drivers side and bank 2 pass?? and is sensor 1 the front o2 and sensor 2 the rear just a little confused here

[metalmulisha777]

a guy at gm told me Bank1 is the o2 that is on the same side as the #1 cylinder and that sensor 1 is infront of the cat and sensor 2 is after the cat so i guess i solved my own problem but maybe someone will find this useful...also the color of the wires you need are for the driver side purple/white and for the pass side purple

well my dumbass assumed that the purple wire would go to the pcm which it prob does but the thing is in the haynes manual it says #34 but there is a diff color wire in the pcm in #34..... i just assumed that the 34 was in relation to the pcm pins but i guess not .... so does anyone know where this purple wire is located for the o2 sensor???!!?!??? on ls1tech someone said it was #68 i dunno what the hell to do lol

I tapped into the wire at the pigtail on the 02 sensor. Thinking I didn't want to muck with the PCM wiring harness in case I ever wanted to take it out.

I just installed a autometer air fuel guage and it is not working...I tapped into the #69 purple with white stripe wire and nothing is working. The only thing it will do is light up and stay on rich and nothing else...[/b]

its supposed to be on #68.[/b]

this is a post over on ls1tech give me feedback im just tryin to figure this shit out.....

Your going to wanna use the #3 pin i believe, if you face the o2 sensor plug with the clip part facing upwards, its the bottom pin on the left, and one right above it you can use for the ground.

the #3 pin on the pcm?

this would be so easy if someone had a picture .... lol
