Ok, I just installed my SAFC II. Everything seems to work great. I thought I would post the wiring here.
--SAFC II Wire Color-------ECU Wire Color--
Red (Power)-------------->Black/Yellow (+B on far right of connector)
Green (RPM)-------------->Green/White (IGT)
Purple (Knock)----------->Clear (KNK)
Grey (Throttle)----------->Black (VTA)
Brown (Ground)---------->Brown (E1)(Goes closest to ECU)
Black (Ground)----------->Brown (E1)(~1cm further down than the other E1 tap(farther from ECU))
Yellow (AFM)-------------->Yellow/Blue (Vs)(going out to CPU from SAFC)
White (AFM)--------------->Yellow/Blue (Vs)(coming from AFM to SAFC)
The Yellow and Blue wire is the only wire that gets cut. All the other wires you just splice into.
The SAFC's brown wire gets spliced between the ECU and the SAFC's Black wire. In other words both the SAFC's Black and brown wire get spliced onto the ECU's Brown wire but the SAFC's Brown wire needs to be the one closest to the ECU.
I hope all this makes sense.
This was done on an 85 P Type with Manual tranny. Use this info at your own risk. Please dont blame me if you wire it this way and you fry something. Always double check your wiring against a reliable schematic for YOUR car and the SAFC II manual.
EDIT: See the following post for issues using the SAFC II on an 82-84!!!
