Ok, so you yank the fox wheel off and this is what you have. There are three spring-loaded pins that ride on the disk on the backside of the wheel. Aparently three was all Ford needed to get the horn to work as well as the cruise control. They didn't change much, because the SN95 wheel also uses 3 pin connectors.
That means if you have cruise control, you would still be able to keep it. You'll just need the wiring diagrams for the 87-89 and the 94+ Mustang.
My car does not have cruise control, so I only have two of the pins in use. A POS+ 12V and a ground. Pretty easy for me so unfortunately I won't be researching how to make cruise control work...since my car doesn't have it
