I don't know about your watch TV switch, but the other two are both taking power from fuse 13. Check the voltage at fuse 13 You should be getting 12V.
Good luck,

Ok I am somewhat confused as to what you are exactly talking about. If the problem is that your cruise control won't work, and you have traced a problem to a green wire that goes from the third light to the brake light switch.....and that wire always is carrying 5 volts of current....?????
Then the problem MAY be that somehow a rear brake/ turn signal bulb has been changed, to an improper bulb. These should be 2 fillament bulbs known as #1157. Some times these are replaced with single fillament bulbs, #1156.. that can cause a rare backfeed of voltage.
This is just a guess, but I have seen bizzare things like this happen.

Without taking the time to verify, I'm thinking that the green wire you are referring to is your brake light circuit, and that before the brake light switch, it should always be hot with 12 volts. It operates independantly of the ignition switch. Therefore if you have 5 volts feeding the other side of the switch, it is being back fed. This is especially true since it only happens when the ignition switch it turned ON. I don't know what you are referring to (watch TV switch) so I suspect that circuit is the culprit. I'd disconnect that and see.

Oppps, just had a thought.
What about that recall for the switch under the master cylinder? Did you have that performed?
Do you have brake fluid leaking at the master cylinder?

Go out NOW and unplug that deactivation switch on the Master Cylinder

I am sorry, the problem is the five volts in that green wire, won't let my cruise control engage. I also happen to have alpine t.v. Hooked up to a switch and my brakes so I can watch while driving. This back feed also will not let t.v. Come on unless key is off. I did put led lights in my brake lights, but when I unplug harness further up I lose the 5 volts at third light. I will check those led brake lights though thanks I really appreciate it.

Did you actually pull the connector off the master cylinder as you were told to do by Miesk5? and then check the voltage? Having 5V on a line that should have 12V on it indicates a high resistance short circuit or bad connection. That is why I told you to check the voltage at fuse 13. If you still have 5V with the connector off, check the voltage at the output of fuse L in the engine compartment fuse box.

No I didn't wool do . I do still get the 5 volts even with fuse 13 out . I will try these things you suggested this weekend and get back to you, also. Really appreciate it..
FIRES HAVE OCCURRED WHILE THE VEHICLES WERE PARKED WITH THE IGNITION OFF
Foregt the voltage checks; disconnect the switch NOW
then troubleshoot the ckt
I know a few owners who had have their Bronco burn to a crisp because of the Switch.
As for the recall;
I know our former local Ford Dealer was VG at doing recall or TSB work such as on the Child Safety Seat, Tether Attachments;
while at same time, others have said that their dealers knew nothing of this ( & "couldn't find the info on it" or wouldn't do it.
and for the Cruise Ctrl Deact. Switch Recall;

Thank you very much , and understood. The green wire behind the brake switch should have 0 volts., unless the circuit is energized. The green wire with the stripe is constant hot. I lose the green wire at mfs switch. I unplug mfs switch and still 5 volts. I dont know where to go next. I lose wire in loom under dash.schematics say goes to engine controls.?....but where?
Okay it started with my cruise control stopped working. than I had a new t.v. Put in and guy told me I was getting back feed in brake circuit 511. Than one day I noticed my third light, which is led is dimly lit when it should be off. I tested circuit and kept getting almost five volts on a circuit that should have zero. I traced it up into dash up past brake switch to mfs switch, till I lost it in loom. I posted here and could not find right answer, even though many good suggestions. As I kept researching found something on f150 forums. They were saying that installing led lights have caused a few people to lose there cruise control and load resistors can fix the problem . Can any one elaborate.?
