This has been on my to-do list for many years. I remember reading through this thread and your very good instructions, but never got around to ordering.
How much is it again?
Thx

Hey Ed, did you guys figure out if these would work for a 968?
I have a 944 S2, if it would similarly work for that too, I would love to order one of these as well.

I don't know for sure whether st0ppy ever got a unit and installed on a 968.
The main configuration that won't work is a dimmer rheostat that's part of a headlight switch / instrumentation lighting dimmer combination where one side of the rheostat is internally connected to other circuitry and can't be isolated ("can't be isolated" in the sense that there aren't two rheostat terminals that aren't connected to anything else).
I'm hoping that others with more knowledge about 944s will chime in here.

What about front lighting w/ a string of LED's?
Pick up a string of lights, put them up,
wait for sunset, and check out the look.
i front lit my instruments 12 years ago.
fantastic presentation, perfect light level ....
a blissful, life changing event.

For you 944 S2 guys, based I what I see in post #279 in this thread, either the "AILD-1 connection kit for '90-'95 Porsche 928 (soldering required)" or the "AILD-1 connection kit for '90-'95 Porsche 928 (crimping required)" should work. If you're comfortable soldering, that first option makes for a cleaner, nicer installation.
There's more potentially useful information in post #168.

The "50%" you might be referring to is just what happens if the rheostat is or becomes disconnected. It just guards against the instrument cluster going dark if there's an unexpected wiring or connection problem.
There's no reason I can think of to select anything other than configuration "G1" for any model year 928.
