Wiring Question;

Can someone help me identify these two jacks? The wiring harness is a 95 M3.

Thanks!

I'll post another pic in a couple of minutes, for better references

[sushipower]

Here is another shot...
AFM - air flow meter?
IAT - Idle air temp?

Thanks guys!

One is the O2 I think and the other looks like IAT but pull the covers back and look at the wire colors. Refer back to the bentley.

O2 sensor and reverse light switch

oh and double check that throttle body fitment

[sushipower]

Got ya, thanks! If you're not running the O2 sensor, can i just tie it up?

[Farbin Kaiber]

Oh, it's just not routed to that side of the engine. I see now.

Why would you not run the o2?

[sushipower]

Still unclear about O2. Thanks, for your help guys!

[Farbin Kaiber]

What we are wondering whats wrong with your car to not have an o2?

[sushipower]

Where should I plug into? I’m not running cat just straight pipes back to the muffler. Can I plug into the Headers?

[Farbin Kaiber]

you can drill a hole, then weld an o2 bung into said hole. Then thread said o2 sensor into bung, then plug into connector.

[sushipower]

Can I just use the one on the headers? or does it need to be down below, just before the cat was?

gazellebeigem3, did you see something wrong with the trottle body?
