Mods made by P.O. What do I have with this engine bay harness?

That silver device on the verticle section of the fender IS the regulator, and the ignition box is right behind the washer tank laying flat.
It's been a few years now, but my 73 Dart had exactly the same layout when I got it as the picture I posted.

Thanks again. The vreg I just bought looks like this. Made in China, BWD branded
