OK, i've already done a damn search, so dont tell me to search. I've looked on vfaq and google and still cannot find my answer. I was using a greddy turbo timer and just got an apexi from a buddy and he didnt have the instructions. I hooked it up with my HKS wiring harness, hooked up the ground to vehicle chassis, hooked up the e-brake line(gray wire) to the e-brake, and hooked up the A/F(white wire) to pin 76 on the ECU. The timer works fine, but my o2 voltage on the timer is reading like 1.5 to 3v. It reads 3v when i'm at WOT. So my question is, do I have the A/F wire hooked up in the correct line? and/or do I need to use a ground from the ECU?

Someone with knowledge bless me please...............
