ABS problem is solved, in the end I just took the plugs off the Spec S loom and plugged it into the existing computer and that seems to be working, ABS malfunction light comes on and off as it should.
Turns out the plug difference is not to do with Spec S and R difference, rather a model year thing. Mine is a late model with 85F20 unit, the loom is from an early model with 91F00 unit. At some point the ABS units changed over from 85F00/91F00 to 85F20/91F20. The 85 ones Spec S and 91 Spec R, plugs are the same for both 00's and both 20's.
I looked up the check engine light behaviour in the manual and it is normal for it to stay lit until the engine is started so I'll assume there is no problem there.
Took the sump off the other day to swap it for one in much better condition. The oil pickup looks a little dubious so I am going to replace it with a new one, this has set back the oil filling situation. Has given me a little time to sort out the oil pressure switch though, the S15 switch connector doesn't fit onto the S14 switch so I guess I'll just swap the switches over.
I'm going to need a boost gauge for it, saw this one and it looks really handy with the oil temp on there too. Depo any good or a load of tat?
