I used OEM parts to make a mini harness and appears to work well.
Originally, I had planned to repin the brown/green connector but I could not find an easy way to do it, and Amazon pin removal tools are bunk and did not work.



So, the bottom white connector hooks up to the brown/green connector with clips coming from the fuse box?? Or idk it comes from somewhere

Then it medusas into 2

Top left goes to your new happy robot with the dual cig lighters.
The top right goes to the cig lighter in your center console.

16awg wire is available at any home Depot/ hardware store, but for some reason I ordered 14awg online which ended up being too thick but oh well..

If you're recreating this, some advice:

I used 14awg wire but it was too thick to crimp properly, if was doing it again I would do it with 16 or 18 awg.

Order extra pins if you're a dumbass like me ( they are cheap )

Pay attention to pinout of the 2-cig happy robot piece as the pinout is the reverse of the connection to the car (brown-gnd and yellowgreen-vbat in my car)

Finding space for this is a challenge due to length of the happyrobot cables in here so you may want to buy an extra black/female pins for the new dual port cigarette lighter in order to shorten it's cables which are very long.

Maybe pack it with dielectric grease if you don't trust exposed copper.
