Blinker Genie Wiring - Front Marker Light Problems LED

I have done a lot of searching for answers and watching YouTube videos, but hoping someone can provide some quick help. I changed the front facing turn signal/marker light to a Lasfit LED. In doing so, I got the double green arrows permanently on when I turn on the lights. From what I've read, this stems from the 2 wire connection to the side marker light. I purchased the Blinker Genie 2 which turns a 2 wire light into 3. How do I go about wiring this up? I see a brown/tan wire and a black with yellow stripe going to the side marker light. I assume I'll need to cut that off and wire into the blinker genie, but want to avoid messing anything up. Hopefully someone has done the same thing.

Thanks that's what I figured just double checking. Only reason I'm doing it this way is because I am just replacing the bulbs not the whole light assembly.
