This is a great post, thanks for making it a sticky. I've been dreading the tank lift, but not so much when I have a visual reference to follow.
To date I've been able to wire in the Eastern Beaver headlight relay and a PC-8, that is running many things, without removing the tank. I've done it mostly by routing through the left side, under the tank and over the radiator, following a factory bundle. It takes a bit of patience and effort to fish some of the wires, but wasn't too hard.
Now the air filter..I guess I can't avoid that.
Thanks for the how to on how to!
