I read that a 96-98 PFC will work on an automatic without any problems here. I also saw that Knightsports makes an adapter for 93-95's to convert the harness to match 16 bit connectors.

So if I used the adapter and a 96-98 PFC, would it work on my '93 auto? Has anyone tried this?

If this works it would be a good option for auto owners to retain the hold function without having to run the PFC piggybacked.

 

If you read the post better it says he has an '98 FD.

 

That's exactly what I'm talking about. So if you upgrade the wiring of a 93 to the wiring of the 96-98 models, the PFC would work.

But, would the PFC work with only the adapter? What changed on the ECU from 96-98 besides the upgrade from 8 to 16 bit? What functions on the 96-98 models would you not be able to use on a 93-95 model?

 

the solenoid rack was completely changed so who knows how wiring was changed for that.

 

Oh I was assuming the tranny or the tranny ecu was changed.
