I think this connector(pic) in a 79 f250-460/c6 is part of the CC.How do I hook/bypass it to get it working?The wire color is: black,red-yellow,red-yellow.Thanks

 

I don't see these color wires in the system. In the left portion of this picture should be the speedo cable. If you have cruise, your cable from the speedo head should be very short, and barely it make it through the firewall, and it should plug into a little round pot metal piece with wires coming out of it. This is the speed sensor for the cruise. Then a longer cable continues out of this sensor down to the tranny.

You should have a darkgreen/white and a black connected to this sensor. You should also have a servo hooked to the throttle with 6 wires coming out of it. Both sets of wires should run through the firewall and go to a control box mounted under the dash. There will be one other wire going to the steering column for the controls, one for power, and one going to the brake light switch.

 

Everything is there like you said.Maybe this(pic) is throwing me off? I guess I should be asking"How do I trouble shoot the CC system?"





Also have trouble with these guys,but I just bypassed them and used a coil wire to get it up to the horn pad.Any other trouble shooting tricks I can do? Thanks for the help.Just trying to get it working again.


Yea two switches for the brake,one kind of on the rod/pedel and the other one on the pedel.

 

The above picture doesn't look like the cruise system diagram to me.

And I wouldn't trust a coiled wire behind the steering wheel. You might just want to mount some switches for the cruise under the dash.

 

That diagram say's "Throttle Act" that's where I get lost.I see the other dia with the 6 wire,two plug,been working off that one.The coil is like a mike wire coil from a CB.Don't have a clue how to wire up some switches for the CC.One wire for the horn(works) and one the CC.Thanks again.

 

Look for boxes in the diagrams that says "speed control amplifier", "speed cable sensor", "speed control servo".

Do you have a meter and know how to use it? If not, you need someone to help you who does know how to use it to do some testing.

 

The diagram was for the throttle kicker for the A/C system and has nothing to do with the CC system.

 

Yea I am pretty good with the meter.I'll get it,just needed a little direction.Thanks subford that gets that out of the way.

 

The CC wiring should look something like this:

The top mech switch is ON,bottom switch(brake?) is off with the pedel in the upright positionTo top goes OFF and the bottom goes ON when the pedel is pressed.
Is this right?
I am trying to test the ON switch to the connector at the Amp(hit ON and should see something at the meter).I have a good idea what wire it is(I think),BK/GRAY.Can you tell me what that color it is? 79 f250 460-c6

 

Is this an after market CC system?
There should only be one stop light switch on the brake pedal.
There is a vacuum switch that the brake arm releases to drop the vacuum off the CC system.

 

No,stock Ford stuff.

 

This is as close as I can get to a 1979, it is for a 1980.
