Glad that you were able to accomplish this.
On a twist though, my truck is a 1969 but started life as an M-726. The data plate was missing but there were just too many signs of how it began its journey. It didn't have a hood-mounted air cleaner. It didn't have a governor. But it did have an electronic turn signal. I wanted my truck to reflect the two trucks that I drove whilst in the army. So, being the renegade, I converted my truck back to the old style distribution relay box with all NOS parts. To my surprise, it worked and no wires smoked.
Thanks for sharing all of your thoughts. And a special thanks to Ron Boltz for his tremendously helpful, clear to read wiring diagrams.
