Air Fuel Gauge Question

Ken 02 · 10-19-2003, 02:33 PM

I know i have to hook the af gauge to the ecu to get and o2 reading, I've heard it goes into b17. Is this correct and how do i determine which is b17 since nothing is marked?

Thanks.

Yep its B17. Check this link to find the location and any other ECU wires you might wanna know.

this thread has been dead too long...

yeah i tried D19 (front sensor) but that didn't work - just got a single green light on the "rich" side. B17 works, although the light show in this placeholder gauge gets old and distracting kinda fast.

new link for that pinout http://northursalia.com/modification...ng/wrxpin.html

This ancient thread needs to remain dead, and this type of gauge needs to be left in the box as it's totally worthless-
