Thanks, that is a beautiful 912!
This info will be handy, especially the coil shared on the heater relay would have been hard to figure out! The newish MSD digital 6 ignition still need a coil.
Hope to get some time to work on the electric system later this week, I ordered suspension parts from our host last week and next week I will try find time to work on suspension. (My vacation is running away between house painting/maintenance at home and playing at the garage.
