Anyone flex fuel tuned can help? Trying to wire ethanol into my evap pressure on ecu. Pin 102/gray wire is what i read. Mechanic had a different color wire listed in his manual but when we looked at what we thought was #102 it was gray. Now getting codes p2127/2138 and the likes saying throttle position/switch is off so starting to doubt i did the right wire. Goes away when i reconnect the wire. Looked through service manual but havent had any luck
Edit: asked VQ group on facebook—it could be a blue wire, it could be a light green wire, could be gray, but sounds like my gray wire goes to 103
Update: on my g37 it was a blue wire with gold marks, right next to gray wire (103). “EVAP” pressure sensor read .53 at 9.8% ethanol, now just waiting to see what’s next
