how do u hook up the air/fuel guage? i heard that u need to hook it up to the o2 sensor from the ecu. i have a 95 honda civic ex. it's a obd 1 so which color wire is for the o2 sensor?

 

You don't need to hook it up to the ecu, it might just be easier rather than running wires through your engine bay. What ecu are you using?

 

Do yourself a favor and just throw it out now. When you find out how useless it is you will later. Mine just shines a nice green light.

 

i got the p28 ecu. for obd 1

 

D14 on the ECU harness. Its a white wire. I believe mine has a red stripe on it.

Look there for a visual. Good link for general car wiring. most things can be tapped off at the ECU and makes wiring in general easier.

 

Looks better too.

 

white wire on the o2 sensor, do yourself a favor and wire it on the harness side of the plug, so you can still unplug the o2 sensor and pull it outta the car without troubles.

also, like it was said before, those things are junk. I've got one and I'll be replacing it with EGT soon.

 

thanks for the inputs guys. i know it the guage are junk but i'm just gonna use it for now.

 

they're good if you enjoy a light show :P
