Hey group, I'm a little out of my element here. I'm trying to install a radio on my Road King, and I want to use the ACC switch to turn it on and off. The radio has 3 wires and the DT connector has 4 terminals. I bought a set of DT connectors with pigtails.
The first picture is the wires coming from the radio, green wire is ground, red is power, and the black goes to the ignition switch. The other pictures are the connectors I bought. This is where I get a little confused. Where do I connect the wires? I have also attached a wire diagram as a PDF to help.
The accessory connector is under the seat. You should be able to ring it out with a multi-meter. I believe only 2 pins are used but would have to check to be sure. The stereo will need constant power to keep memory so there is a slight parasitic draw. Don’t forget a render when it is parked for long.
Not too sure what year your bike is but this might help you figure out the wiring. I have a USB power port connected to mine and run along the harness under the tank to power my phone or GPS on the bars. I use the ACC switch to turn on and off.
