The front LEDs are easy. The three wires match the three turn signal wires. Same for the back if you're intending to just have turn signals.

To make the back leds operate for both brake and turn usually requires a run/turn/brake module of some kind, whether its 2 wire (single color) or 3 wire (dual color). Both turn and run/brake wiring input into the module, and the output wiring goes to whatever led lighting you have.

Check the wiring all the way back under the seat to the fuse box to see if any module has been wired in. If not, I'd recommend getting one.

Is the chromeglow under fender strip dual color (3 wire)? If it's a single color, I'd just leave it as is and tap the module in upstream. If it's a 3 wire strip I'd wire them all together with the module so that all your lights would get whatever other features from the module you've chosen.

Those are the ground/brake/left/right wires then. Sorry, its been so long, and I've only used single color strips. I see whats happening now in the video of the strip. It never actually turns off the red led's when the turns are switched on, it only flashes the amber led's over the top of them. That makes sense as to why he's just wired them straight into the bike without a module. The run brake wires are just voltage. The run wire is continuous low voltage. The brake wire applies a higher voltage only when engaged. I guess thats how he was able to splice them together. I'm surprised the custom dynamics led's won't accept the same wiring hookup.

By contrast on my bike with a run/brake/turn module: When I switch a turn signal on, the run light switches off while flashing. If I apply the brake, the brake light switches on also flashing.

Well, no matter what, it looks like you'll need a run/brake/turn module for the new signals at the least. Tap them upstream to avoid issues with the under fender.

Glad you got it figured out. This is why I love run/turn/brake modules. One module to rule them (lights) all!
