Well, we've already got the '72, so we got a universal harness from Painless, guess we'll just have to see how it goes, we have the factory schematic, it won't be too bad. Thanks for the links, I'll check them out, gonna be needing lots more stuff, I'm sure.
Funny that you say the '73 was the first year with a fusebox... I searched all over this truck for it, even made a post here a while back. Anyway, we'll be putting a new one in here, real soon.
