Searching for wire to tap Denali DialDim

Hi everyone.
I'm installing the Denali D7 on my Rocket 3 and they will be paired with the Denali DialDim Controler. It's a system that use a remote and use the info send by the motorcycle to know when your Ignition is on, when you use your high beam, your left or right turn and when you honk. It's a very powerful system but it needs to be tapped on wires to have different functions activated by trigger wires.

So I would really appreciate to have some help to help me to locate a wire for the Ignition, wires for the right and left turns and one for the high beam. I'm looking ideally under the seat since it's not really easy to pass wires to the front on this bike.

I have the maintenance manual so I see the wire diagrams but I'm not use to work with that and have no idea where to look at. So any help would be very appreciated!

Here is a link to a YouTube Video explaining how the Denali lights works with the DialDim remote.
And this link if for a little longer video (38 min) showing an installation and the result.

And here is a picture of the bike with the Denali D7 installed.

I tried to figure out how to fing those wires today but it was getting late. My first idea, as explained in my first post, was to, as much as possible, to use wires from the back of the bike. For the Ignition my idea was to use the USB wire in the comparment under the seat andtrybto find the left and right signal at the back. But I had to go up to the front to connect to the horn and didn't want to bring only a tiny wire alone. So I bring all the wires to the front. I change the horn for a bigger one and the trigger wire was connected. I used almost a complete shrink tube to pass all the other trigger wires together to the front end, under the front cover. I think everything will be easier to connect from there.



Now I need to find those wires to tap the trigger wires on them. If anyone could help me with this that would be very appreciated. I'm looking for :
- Ignition (I should be ok with that one, I will use the wire for the Din connector
- The high beam
- The left turn signal
- The right turn signal
