How do I tell if my truck 3/4 Ton truck listed above has cruise control? I know is seems simple. But the truck has a transducer. The question leads to me hooking up my lamp switch for the breaks. I can't find a absolute fact that the truck didn't, have it?

Sure, here are the locations for the cruise control parts. To see if the truck has cruise control, you will need to lift the hood. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

Ken,

Thanks for answering my question, I've added photos for your review.

This leads to my next question, trying to get my brake lights to work, depending on the switch which I purchase. I've tried three different ones.

See photo's below of under the hood.

If you have some ideas about my break switch, here some info
I've purchased several new switches that can't seem to get the light to work.

- Power is going to the brake switch.
- Fuse is good and tested both sides of the fuse so it's not the circuit board.
- Replaced bulbs in both outlets.
- I am receiving power to the back end as hazards and parking lights come on.
- No power to socket when brake is applied.
