- 89+ - Yes, same mod as described above.

- 87'-88' - Yes, but one additional wire (pin A) is needed to add a speedo signal to the kickdown relay (89+ get this speedo signal from the digital instrument cluster), speedo signal would have to come from the differential speedo sender which provides signal to speedometer and cruise control.

- Pre 87 with 4-speed auto - No, not recommended, GTS throttle valve switch may not adapt, pre-85' CE panel design has earlier relay sockets which may not work with later GTS kickdown relay.

I can't say that I'd do it on my '88 as I already row the shifter in the same fashion. Might re-think that when I take my intake off to have it all coated again here soon.

Some specific details and photos of where to get this signal on a MY88 928 would be most helpful.

Not sure if thats directly compatible with the Speedo-A signal from the DigiDash - but its all you have, it is at least close enough that either of these signals can be used to drive the same cruise speed control module between years - so worth a try... I suspect it will work fine.
