I just looked behind the ACC unit and I saw 5 connections numbered 1 thru 5 from drivers to passengers side.

I tested the #4 (red) and it held vacuum. It went to a controller behind the glove box on the left.

I tested #5 (green) and it didn't hold vacuum. Green goes to a controler below the passengers windsheild.

Does anyone know what #'s 1 thru 5 operate? Looks like I need at least a #4.

TIA,

Craig
