So, is your car a 1990 spec Syncro? Or did you just upgrade it to CE2 wiring?
If the car was a 1990, it should have already been CE2, so no conversion would have been needed.
As far as the connections for the wiring/vacuum for the freewheel lockout solenoid, the easiest way to get things going would be to find yourself the wiring from a CE2 Syncro.
Which transmission are you using for your ABF, 020 or 02C? If 020, I wouldn’t expect it to hold long… [xx(]
If it’s an 02C box, I would assume that you would need the corresponding wiring harness for the 02C reverse switch, as it’s different from the 020 piece.
