I am putting in an a/f gauge in right now and dont know where to tap the wire at for the O2 in the ECU. If anyone out there knows from experience which pin# or color coded wire in the ECU is please let me know. Ive already got a good 12V and ground going, just stuck on where to tap into. If you can please let me know something ASAP that would be awesome so I can get this guy working right away. Thanks guys....
