The MPIV picture is incorrect - the connection to the wiper motor shown is for wireless noise suppression. The actual MPIV is vertically below (hence the confusion in overhead maps), but in the cabin on the left side of the steering column (in a LHD car). It is critical as it has many ground wires, but it is also protected from weather.

You guys are AWESOME! Thank you so much for adding those!
Going over the electrical system is my first step in my restoration job, and having these photos handy make the job much easier.
I started work on the fuse panel this morning. The fuses for the AC & blower were all blown or melted slightly, which is a bit worrisome. Now on to chase that problem down, and also do a 53 Relay Refresh too.
Thanks all!
