Im going to add to this thread as I just did some research and completed some tasks. I replaced the steering wheel, turn signal switch, cancelling cam, and plastic wiring connector at the base of the steering column that joins the turn signal wiring harness to the under dash harness.
I have a 73 Bronco and the steering column is from a different year. It has a hazard switch on the column. 74-77 has the hazard switch on the column but if your ordering a steering wheel mounting adapter, the diameter at the top of the column with the steering wheel removed is is aprox. 3 1/2" for 66-74 and around 4" for 75-77. Mine was 4".
All my wiring was butt jointed at the base of the steering column....I couldnt sleep at night if I did something like that. Butch the floor, butch the dash, butch the wiring harness. Not on my watch. So I tried to locate the horseshoe plug connector...nope. Looking at the pics of Painless and Centech wiring harnesses......the connectors sure look like GM stuff. I ordered the complete GM connector with all the terminals from Speedway for 9.99 part number 910-500428. Crimped and soldered it together and plugged them together. Waiting to see if my Ford rejects the GM transplant...Nope, shes alive.
The cancelling cam from Toms Bronco parts shows a 1 leg cam on his web site ( i cant find it in his catalog) but when I got it, it had 2 legs....someone mentioned hunting for a 2 leg cam...it is what I received....passing that on.
The new steering wheel looks awesome, everything works.
You guys have alot of great information on here. I try not to post questions and search for the answers. Pretty much can find anything....Thank you and this is my attempt to give back
