EdwardB’s 35 Hot Rod Truck Build - Well Traveled

[edwardb]

A couple of suggestions for the cruise control:
- make sure the brake sense wire is connected to the load side of the brake switch. Otherwise the controller will receive 12volts continuously, signalling it that the brake pedal is depressed.

- some controllers need to sense a path to ground through the brake lamps when the pedal is released. If the brake lights are not connected, or are LED, there may not be a path to ground. Try connecting a standard globe temporarily in the bra circuit to give a ground connection through its to filament

Thanks for your post and for following my build. Have both of these points covered I think. Per the instructions, this unit has one of the controller wires connected to the hot side of the brake light switch. Then another wire to the cold side of the switch (only has +12V when the brake pedal is pushed) has to be grounded for the system to work as you said. And yes this build is 100% LED. Dakota Digital has that covered in their instructions and shows installing a relay to ground which is broken when the brake pedal is pushed. The proper operation of that relay was one of the things their tech support had me confirm. This could easily be user error (wouldn't be the first) but everything we've checked is wired and working as it's supposed to and exactly per the instructions. All the voltages on the various pins are what they're supposed to be. But on hold now until it's a driver and see what happens then.
