Hi all,
I wanted to install a secondary 12v outlet in my 2019 Model 3 but wasn't content with other solutions, which included splicing the existing wiring or dragging a line to the battery. It was difficult to track down the parts list, but I managed to compile a list of connectors and terminals needed to make a Y adapter to connect in-line with the existing 12v outlet and the wiring harness providing power to it.
In the below photo, I worked with a friend to create an adapter that continues the existing connection to the 12v plug in the console, but also provides in parallel a SAE quick connect plug which can be routed down through the console without need for disassembly.
Here are the parts I ordered from Mouser to match the existing male and female connectors for the 12v outlet in the console:
I also purchased this SAE quick connect extension cable which we spliced into the Y: https://a.co/d/d8tnHEI
(I chose SAE because it allowed me to route the wiring downwards through the console without having to do the soldering work inside the vehicle. It also makes the line out discrete when not in use)
Finally, I purchased this SAE quick connect to 12v connector adapter: Amazon.com
(I chose a medium length cable, but you could easily select any other length needed - which is one of the reasons I chose to do a SAE connection)
The friend who helped me used his own 14 AWG wire for parts of the Y we made, but you can easily splice the extra off your extension cable.
I got lucky with ~14" of lead on the SAE plug - I'd recommend closer to 18-24" to be safe.
Here are some photos of the install and outcome:
I'm up to my attachment limit on this post, so I'll try to reply with the additional resources I located for disassembly of the console.
