Hi All!

I am just about to put my Apexi TT into my 95 WRX but need to know how to hook up two of the wires.

If any one has hooked one of these up can you confirm that this wiring is correct:

RED wire on turbo timer to 12v+ (Black wire with white stripes on WRX)
BLUE wire on turbo timer to Ignition II (Black wire with blue stripes on WRX)
GREEN wire on turbo timer to Ignition I (Black wire on WRX)
GREY wire on turbo timer to hand break relay

what i am stuck with is:

BLACK wire on turbo timer to ECU ground (????)
WHITE wire on turbo timer to ECU front o2 sensor signal (????)

these two need to be connected @ the ECU. Can anyone tell me or show some pinouts of the ECU ground and front o2 sensor signal wires

Thanks guys
