Retrofitting a 1989 Supra climate control module into a 1987..
 

Hey guys,

I've seen images online where people have put the all-black climate control modules into older Supras, and I was just wondering how difficult this might be or if anybody might know the specific process.

It's plug-&-play, a direct-fit replacement. Just remove the bezel around the control unit, remove (iirc) two screws and the wiring plug from the old unit and swap in the other one. Plugs and stuff are the same.

yep piece of cake so easy easy I did it
