Wiring dilemma
I have an unusuall situation here. I have a 72 F100 body on a 78 Bronco frame. I am having issues with the wiring of the steering column. The column is from the 78 and does not connect to the 72 harness. Can any one tell me the wire color to Wire color corallation in a 78 from one side of the column harness to the other. I have searched every where and cannot find the column side of the connector colors anywhere.

Do you have a local library? A lot of libraries have tons of technical manuals for vehicles. Considering that you have a very custom job there (not one that's done every day for sure), you're probably on your own on that one.
Find the wiring diagram for a '72 and the diagram for the '78 and lay them side by side and match. What all is there to line up? Is it just the horn? Or do you have cruise as well? If it's just the horn, it should be pretty simple. You could almost just guess and check.
PS: A dilemma is when you have two or more choices and can't decide which to choose. Like, do I have beer or wine tonight?

The problem is the turn signal switch. I have wiring diagrams for both but not a diagram for the column itself. The wiring of the turn signals doesn't make sense to me due to the way that Ford wired them. I can use a multimeter as a last resort but trying to find a quicker way. All I really need is a good picture of the steering column harness on the chassis side and I can figure the rest out.

What about that website? $6.99 for the diagram you're looking for. Might be worth the pennies.

So, I see your dilemma now. Sorry, took me a bit... as long as you can determine which wires (colors) are coming down the column to the chassis, you should be able to get the switch and column wiring from one to work with the chassis wiring from the other. Is there any way to check wire colors and match them based on how they route from the switch? I can't imagine the actual circuit wiring is any different since I don't think turn signal wiring changed much at all before the advent of much more sophisticated electrical systems. I would think your worst dilemma is changes to the wire colors.
