Cruise Control/Swap
I am wondering if there is a way to take the cruise control system out of a '79 F150 and put it into my '78 F150. Also, would I have to use the stock steering wheel with the controls on it, or could I keep my aftermarket wheel?

It is possible and not too difficult if you have a complete donor truck. It would work best with the stock wheel. But if you're handy with circuits, you could build something that would imitate the controls on the stock wheel. The stock switches are not just switches. There are resistors involved as well. A wiring diagram will show the values of the resistors. I don't know if you could mount this on a custom wheel.

It depends !
The steering wheels is the least of your concern although they swap straight over.
What are the last 6 digits o the VIN # on the 79 ?
Cruise control swap
Parts required listing.
Cruise Contol module (Underdash)
Cruise Control wiring (Underdash)
Cruise Contol actuating device on Intake
(Carb linkage chain,bracketry,Vacuum pod)
Vacuum actuation device harness
Vacuum Canister and hose to rear of intake.
Brake Booster FT-38 ,or FT-43
Brake Pedal & Pedal Assembly
Cruise Control shutoff switch
Horn relay & wiring
If the 79 was built after DJ0001 ...You will need the special brake pedal and Brake Booster from the 79 built before DJ-0000 or a 78 with cruise.
It isn't really a simple swap that some people think it is.

Then it won't swap over.
anything after DJ0001 requires a special booster because it is a different mounting.
The 78 requires the fulcrum booster..
The 79 booster after DJ0001 is a straight thru to pedal booster.
I have photos if you need to see.

cruise
Do you really need to have the brake switch hooked up? I thought that just kicked the cruise off if the hazard lights come on. I figured the break in the vacumm line is really what made the cruise go off.
I am trying to do this switch also. My donar cruise has the amp. I think it is out of an 84.

Nope , You NEED both switches
One is for brake lights
The other for cruise shut off
This is where the Special Cruise control Brake PEDAL comes into play.
That's how the system works.

It was also part of the design wiring allowing for the incorporation of cruise control into a Main harness as an option (also cost factor) for all models.
The Plug & Play concept with minimum changes.
They already have enough trouble with the elaborate Turn Signal Switch wiring that cause tons of problems

I just pulled a cruise setup from a 77 to put in a friends 76 before seeing the list. I did not know to get the brake booster and pedal if those are nessceary I guess I'll have to go back for them.
I got evrything else including the speedo cable and speed sensor wich was left off the list. I also pulled the steering colum and steering wheel. I'm wondering if the 76 steering column in the truck I am transplanting the cruise into is wired for the cruise or if I'll need the 77 column. Also the steering wheel from the 77 is very cracked, can I put the horn button with the cruise switches from the 77 onto the 76 steerng wheel? Thanks
