Thread: U13 ECU pinout

Need help here guys.

I tried searching the net and reading the B13 ECU pinouts (some say that U13 and B13 share the same pinouts), but U13 has pin # 25 while B13 has none. I can not determine the # 25 pin.

Aside from this, can i confirm that # 45 pin is Fan Switch.

B13 2.0 has no pin # 45, while
B13 1.6 has which is Fan Switch.

Please somebody help me.

Thanks.

I thought I had a U13 pinout, but I guess I do not. Are you just concerned about putting it in your car? I had a U13 ECU in my NX2000 with original harness and had no issues if that helps at all.

that's what i'm doing.

If you had that in your NX, then can you please check what is the pin # 25?

This will really help me...

bump, before you guys sleep.

Sorry for the late reply. I got rid of my NX almost a year ago, or else I would gladly help you out. If it helps at all, I just threw it in the U13 ECU and never changed anything in the wiring, and I never had any issues really.

this weekend i will know bud. i didnt crank it because i changed fuel lines and clean the gas tank. i will crank this on weekend.
