I want to use the cigar lighter socket in the load area of my 2022 Subaru Outback to charge a LiFePO2 battery. I understand that these circuits should be limited to 10A (although the Subaru has a 20A fuse for this circuit) and I have a charger which will limit the current to 10A.
Unfortunately I am getting a lot of voltage drop across the socket -- I see 9V at the charger when it draws 10A. The positive terminal of the cigar lighter plug gets very hot.
So I want to remove the cigar lighter socket and replace it with an Anderson connector.
I don't know how to get the cigar lighter socket out of the trim. As you can see in the photo, there's a hatch which allows me to reach the socket from above, but I don't understand how it's retained. (off topic: what's that purple thing with "K" on it? The plastic cord seems to head towards the fuel filler.)
