Help with DK push button switch on a CanBuss Dyna
DK said they had a customer say they made their push button ignition switch work on a CanBuss Dyna, but the only information they had was that he used a 200 ohm resister. The bike has a 2 wire harness going to the factory switch, and the DK switch has 3 wires. Any help would be much appreciated. Thanks

I don't know about the DK switch but HD's ignition switch as you suggest, has two wires.
One is a ground wire.
The other is a wire supplying voltage to the ignition switch from the BCM. It also observes any change in voltage on this wire due to ignition switch position.
The ignition switch unlike the more traditional switches now has resistors in it. One is 200 ohms and this is used to indicate the ignition ON position. the other is 800 ohms and is for the Accessories position.
Depending on the position of the switch, the change in voltage due to each of these resistors that the BCM records enables it to decide if the ignition switch is in the Off, On or Accessory position at which point it will turn on, or off, the appropriate circuits.
Hopefully someone with more experience with the DK switch can help on that side.
In a more traditional set up, where should the three wires from the DK switch be located?

Update! I changed the black wire over the fuel pump power then to the speedo power and it's still staying lit at both lovations after I turn off the bike....

I never got to install it before the car hit me in June. I'm still rebuilding the bike. But I thought the black was ground for the LED, and white and red were the +V for the circuit? I got on DK's website to see if they had any diagrams, and didn't see anything. I did see they are now offering a canbus adapter. JFYI

Sorry to hear about your bike.
The white and red wire tap into the existing ignition switch wires with the CanBus adapter in line on one of them. The black wire is the 12v source for the LED ring on the switch. The instructions made it very clear that the black wire wasn't a ground lol.
It's weird that no matter where I pull that 12v source from it's constantly getting power but not fully lighting up the switch.
