Just wondering if the units can be upgraded...or downgraded from digital to manual dial controls. The '90 digi controll is kinda cheap. I like the '92.

Very, very difficult if not almost impossible to do.

You'll need a whole new AC box behind the dash with all the right motors for flap-if you want digital and if you want manula you'll still need to change all that anyways and maybe even some AC line.

I wanted to do it myself too - to switch to manual controls - but it is just too much trouble for a little reward.

Do u mean swapping the electronic CC from B4 with an Electronic CC in a B3.

The newer unit is nicer, i think, anyone actually done it?

I know one guy but he is not on the forums

I'd like to know how he faked or otherwise got around the compressor speed signal.

If you have access to the right used parts you can make a wiring adaptor
