Wondering if you can draw the diagram of how you connect the switches, could you please take a picture how you connect the brake switches, thanks. The bike looks nice with all modern accessories.
Sorry, I haven't been on the site for a while.
Switches are switches and buttons are buttons. You can replace your existing buttons and switches with buttons which have the same function and therefore you only have to rewire them the same. I chose to put my wiring through the handlebars and decided to make all handlebar wiring negative switching only thereby reducing the number of wires needed to run through the bars. That required low input relay boards and an on/off latching relay for the kill switch. Its not the most difficult thing to do but you have to consider if it is worth it for you.
I love the look of new buttons but I have to admit that they are not as ergonomic as the original switches and did take some getting used to. To do it without relays you need latching buttons for the High/low beam and Kill switch. All the others can be non latching (Momentary) and then its just a case of replacing them wire for wire.
To draw a diagram as I have wired it would probably over complicate it for you. Get a multimeter and a circuit Diagram and have fun with it.
