running out of ideas to wire this s-afc???what about you
i have a 91 crx si. trying to install this damn s-afc. im using apexi wiring diagram h-1. when i wire up the power and both grounds i flipped on the igniton to check if it was powering up and it doesnt. when i touch the power wire to the battery and use the battery grounds it works fine. am i using the right diagram? what could be causing the s-afc to not power up. the ecu is recieving power but not the s-afc. im stumped.
thanks for your help guys.

taken from mechanic_b.
Apex-I AFC VTEC controller
for PM6 (88-91 civic/crx) or PG7 (88-89 1.6L integra) ecu application only
V-AFC VTEC controller ECU PIN location
Red & Orange wire splice/connect to A15 (yellow/black)
Green wire RPM signal splice/connect to B15 (white1)
Pink wire VTEC signal output to VTEC solenoid (green/yellow)
Purple wire VTEC signal input not used on PM6 ecu
Blue wire VTM signal not used on PM6 ecu
Gray wire Throttle signal splice/connect to C7 (red/blue wire)
Yellow wire Pressure signal output cut/connect to C11 ECU side harness
Si/Hf = white1 , DX = orange
White wire Pressure signal input cut/connect to C11 ENGINE side harness
Si/Hf = white1 , DX = orange
Black wire Ground splice/connect to A16 (brown/black wire)Engine side harness
Brown wire Ground splice/connect to A16 (brown/black wire)has to be connected closer to the ECU
i KNOW FOR A FACT that this wiring will work on your car. i just wired mine up yesterday on my crx on the same ecu as yours - pm6
good luck

oh, this is actually for a VAFC, not an SAFC. however, the wiring should be EXACTLY the same - with the exception that you wont be hooking up the pink vtec wire. other than that, make sure you connect the brown wire ground closer to the ecu.
