    Has anyone found a source to tap for unswitched (i.e. always on) 12v power in the area to the left and below the steering wheel (10amp fused preferred)? I've searched extensively on Priuschat and there are links in older threads that may have been promising, but the links are no longer valid. Any help much appreciated!

    I think I found a source. The attached diagram is the ODBII port showing Pin 16 red wire as unswitched 7.5a power.

    OBD port for sure has a pin that's always powered. Memory saver cables employ it.

    I checked mine; these connections have continuity:

    Pretty sure this is the information you're looking for. Got this from the DIY JDM Signal Mirror thread.

    Thanks! Your second attachment 132314 looks like the UL2 connector in my diagrams. The 3rd attachment doesn't open for me.

    Does anyone know where the UL2 connector is located?
