This week I ran across an NOS leather steering wheel that is the correct color for the interior of my wifes 2000 coupe. One of the things her doesnt have that I thought was a 'standard option' on cars these days is cruise control. What is involved in adding cruise control to a 2000 Mustang? Is it as simple as adding a steering wheel with the buttons (like the NOS wheel I found) or is there additional wiring needed? When I added the heated rear window all that was required (besides the glas) was the switch on the dash and the wires that plug onto the glass (one ground, one power). The power wire plugged into the existing harness behind the quarter panel trim. Easy. I do have a the wiring diagram book for her car and I will be checking that out too.
