I added Skene P3 brake lights to my 2017 RT using the new Gen 2 Hex EzCan. Using the instructions on the Skene site, the installation does not require tapping into any wires on the bike. The new Gen 2 EzCan allows you to choose any of the 4 circuits for any purpose. And you can set the fuse limit for each of the 4 circuits independently to any value from 1 to 25 amps. Each circuit can manage 10 amps continuously, or peak values to 25 amps for brief periods. The total amperage for all connected devices cannot exceed 25 amps.
Depending on the purpose you select for each circuit, you get a menu of context-relevant choices for that circuit. For example, if you configure a circuit as "accessory" then you can select an adjustable time delay for that circuit to operate after you turn off the power to the bike. Similarly, if you select a circuit to be for "brakes" then you are presented with a variety of brake flashing options.
I used the accessory circuit to power the Skene controller, and I used a single wire from another circuit to trigger the brake light. So, I have used 2 of the 4 available circuits just for the brake lights. But, I have not interfered with any of the OEM wiring. The EzCan has a diagnostic mode, from which I was able to learn that the brake circuit uses a peak of .33 amps.
My plan is to use another circuit for some conspicuity lights mounted on my engine guard-bars.
I was thinking about using one circuit to power the rear auxiliary power socket for my heated clothing. One of the EzCan circuits can be set up to operate with the BMW Multi-Controller wheel. I thought it would be convenient to be able to adjust the heat using the controller wheel. It would be easy to pull off the connector on the power socket, and replace it with one fabricated using the EzCan. But you only get one circuit that will interact with the Multi-Controller, and I decided to use that for dimmable lights.
Other circuits can interact with the BMW controls. The accessory circuit can be toggled on and off using the turn-signal cancel switch -- holding it in for a few seconds. I think the horn button can be configured to flash lights while sounding the horn. I haven't figured out all the options yet.
As an aside, when I looked at the rear power socket, I discovered that the wire gauge is really small -- suggesting that BMW did not intend you to run heated clothing off that outlet. I ended up adding a direct-to-battery connection for my heated clothing.
