I'm looking to move some switches around on my 2018 and want to see if there's a way to avoid splicing into the wires to lengthen them. Specifically, I want to move the 3 switches on the right (PCS, Rear Door Main Power, Rear Door Switch) to the left and put a Switch Pros on the right. There's companies that make switch panels that add extra switches where the little card holder is located on the stock left switch panel (see attached photo). I need to see if there's enough slack to swap the mirror adjustment and the stock switches as all the panels I found like this are for RHD 200s. Does anyone know of a source where I can find the male/female harnesses to extend the wiring? Or, a pre-made extension using the factory male/female connections? I can use posi-taps very easily to do it, but just wanted to see if this was an option.

If you have access to a factory service manual the electrical wiring repair section is quite comprehensive. Shows how to get part numbers off the connectors you can find, and from there you may be able to adjust a digit or two and find female connectors that you could adapt. That is assuming toyota even produces the female counterparts to the male harness ends.

If you can figure that out the harness connector repair pins themselves are easy to work with.. then put them together with some wire and you can build extension harnesses.
