I have a 95 gsr in my 92 eg hatch, and i keep getting CEL code 10 for IAT. I know the yellow/red wire goes to D15 on my ecu, but where does the other wire go? I tried grounding it to my chassis, but it just pops my ECU fuse. I've tried looking up wiring diagrams, but haven't had a whole lot of luck finding the info i need.

Thanks,

I was having trouble reading the diagram on my phone, but now that im on a computer i think i found that the other wire goes to either D21 or D22. As they are both sensor grounds. Does this sound correct?

 

should be D22.

D21 is ONLY for your MAP sensor's ground and nothing else.

 

Alright, thanks! I think i have a pretty good idea of where to run my wires. I'll have to splice into my ECT or TPS, because im pretty sure they ground to D22 aswell.
