I have a printed copy that was obtained from Avanti Motors in Vila Rica. i can scan them and send them via email or snail mail a printed copy. PM me at AvantiRay@aol.com. Oh my, showing my age with an AOL address
I have the instruction sheets for the 87 & 88 dash removal if anyone need it. I also have an electrical diagram suppled by the factory for 87 & 88 as printed by Avanti Motors.
Scanning them now. You should have them shortly. They came from the Avanti factory in Villa Rica when I accepted delivery of our 2002. We drove there with our 88 LSC and purchased many items for the LSC.

Have you found a diagram for the AC and heater controls as published by Avanti? If you still need it, I can scan it and email it to you. The diagram I have is only 43 pages and the AC and heater is on page 35
