You will need the pressure switch off a master cylinder to plug into your wiring. Cruise with automatic has two switches one is already there from the factory the other is the pressure switch in the Maxter cylinder. I would for the short time just take one off a JY truck and plug it into your wiring harness. The other is the brake light switch which all vehicles already come with so you have one already in place. If you have a standard you will ned the clutch switch or be careful leaving that one out since pressing the clutch can and most likely would rev the crp out of your motor.

Would a simple toggle switch work?

I have a 1993 F350 xl. I picked up the cruise servo and the horn cover/cruise switches. What does the master cylinder switch plug look like? The picture on page one of this thread does not look like any of the plugs on my truck. I found the obvious cruise plug, it huge...
1st post, thanks!

Its dark out now but I will take a picture of mine when I get up in the morning. If you took the switch off the donor truck I believe its the only one that will plug into it. I could be wrong so look for a pic or two in the morning.

Has anyone mentioned the year this is coming from/going into? I just skimmed the thread, sorry if I missed it 
My 1987 F150 with the FI 4.9L had the same Cruise setup that my 1987 F250 carb'd 460 has.
-Big vacuum actuated servo on the drivers fender with cable to carb/TB
-Vacuum dump switch on brake pedal.
-Vacuum signal going to brain box in dash
-Speedo sensor behind cluster
It is basically a stand alone system. . .just FYI

If your truck didn't originally come equipped with speed control then your truck most likely will be missing the master cylinder pressure switch.

I have the servo, the "Connector", etc...
My question is, how do I actually connect the wires in?
Also, I'm looking into a 1997-ish Lincon Towncar Steering wheel....Has all the controls....

I fully understand the part of that connector, but I mean, where do the wires go, to ADD the connector...
Mine doesn't have the OEM connector for CC, nor do I recall seeing that pigtail for the BPS...
UGH......

All of that is shown in My POST #4
sorry but it's not in your #4 post. If that's were my connector was I would have already had it hooked up ....
I finally found the brake switch and jumpered it. On the 93 f 350 4 door, it's under the truck attached to the frame directly underneath the brake booster. you cant see it from the top of the truck.
thanks for the help your picture did help, I went to the junk yard and looked at 6 or 7 different trucks trying to find that damn connector. it's in a different location on almost every truck

Maybe you could post up some 92-93 photos of the connectors......
