I have been confused for quite some time by the lack of proper documentation for the Auto AC system on my 88 ST165.. I have the Factory service manuals and until I came across these schematics that were from some "Professional electrical" manual on Ebay I could find nothing else that had this kind of detail. These are very similar to the Factory schematics however additional information was never included specific to the ST165. (even in the ST165 manual.) The pages were already slightly faded when I received them, although you can still make out the pertinent information. I wanted to have these in a non fading format Scanned at 600 DPI each page was roughly 196 Megs. (These are in Windows bitmap format). Noticing this was too large I simply resized each page in Windows Paint to 25%.. So now they are roughly 12 Megs each.. Should be fine. Here is a link to the smaller files.
