i am trying to connect the air fuel ratio gauge and dont know where to connect the o2 wire... i have a 2001 engine with the 4 plugs instead of the 2 plugs for the 2000's

 

I suggest that you buy and install the Auto Meter O2 sensor. I've heard a lot of complaints and had problems myself trying to tap into the stock sensor. You can try, then sauder the wire back if there's problems.

 

If your willing to tap the wires at the ECU, I can give you which wires, but I'm not sure which is the front/rear(bank 1 vs. bank 2) bank? Do you have a FAX number?

You can figure out which is the front/rear bank by back probing the ECU pins and doing a continuity test with a volt meter to the O2-plug under the hood that connects to the FRONT 02-sensor. You can then just tap the 02-plug wire you find. Either place will work, but the ECU worked fine on a 4th gen..

Let me know, but the ECU is a bit of a bish to reach/tap.

 

my friend was trying to tap it to the ecu, but he couldnt find the o2 line..... please give me info about where the o2 is on the ecu
thanks

 

Do you have a ESM/FSM?

If not, you need a FAX number, because withOUT the diagram you'll never find it.

 

 

You don't want people sending you crap.

I'll send it right now.

 

thanks for helping me...
but i guess the fax machine is outta ink...

My friend's shop; he's actually got my friend's 300zx right now. Needs some engine work; AMS f'ed it up and cyl 3 has deadly low compression.
