So, I bought my 1990 Toyota pickup 4x4 from a buddy who had removed the HVAC fan to get to the computer. A rat had eaten through the wiring and he spent the time rewiring the entire box.

But, all I have is a box of screws and nuts and bolts and then the fan unit itself. I don't know how it all goes back together.

Does anybody have a picture or diagram showing how the nuts/bolts/springs/etc go together make this thing work properly?
