There are several wiring harnesses that are clipped to the underside of the dash so you need to either cut the wire ties or fiddle with the screws holding the clips in place.

it took me most of a day to get it apart and a day and a half to get it all back together. Lexus builds the car with precision, and it must be put back together in the exact reverse order to the way it was disassembled. If you have to force anything, it means that you missed a step and you have to go back. It’s an interesting challenge.

I guess if there isn't anything in there causing a few volt drops or charging system related then no point right?

it has to be charging at more than 11 volts for the battery to be charged. Maybe it’s because of where you are checking the voltage from. I use an ELM 327 obd2 reader and the obd fusion app.
