I did a quick search and came up short. I need a wiring diagram for an S14 SR20DET ECU. I am just looking for the location of the 02 censor signal wire for my air/fuel gauge.

Any help would be great  
Thanx

hummm

why not just figure out what wire is signal right on the 02 sensor wire.

then find the same one on the ecu?

White wire pin #29 I think…  
As the other guys said, check for continuity from the O2 sensor end… In fact why don’t you just get your signal from this end?

If you really need the schematic let me know by email.
