You mean like this?

It is amazing what you find surfing the internet late at night. A lot of bookmarks and screen grabs.

Only saved the 68 stuff on my PC for selfish reasons. I think the letters refer to the connector which are on this diagram too.

Steve's already got the regular diagrams like that one. And he's got some outstanding modified ones for the newer ('72 to '77) Broncos on his SuperMotors site/pages you should check out.
But the actual location diagram you posted are relatively unseen around these parts.

Be great to have the keys to them as well. Love to see more.

Hey Steve what's the link to your site? I could really use some 72 wiring diagrams, I have '66 stuff, I know lights were added in later years as well as a brake pedal switch vs the hydraulic 66 switch, but did the wire colors stay the same for the most part over the years?

These seem helpful...

Great stuff you got there Steve83! I had a helluva time printing your 72 diagram, tried all my computer tricks ended up breaking it up into 4 quadrants via screenshot and it printed up nice.

The '72 diagram is a work-in-progress; it's not finished, but I put it up just for reference.

Those are good finds - thanks for posting them.

Hey Jeff,

I have a set of factory diagrams. If you�d like I can send them to you and just return them when your done (if that isn�t an oxymoron when speaking of Broncos?)
