Backup camera connection help

Hello all,
I have been searching through countless threads to no avail.... So my issue is this;
I have a 2010 DCSB that I installed a 2013 touchscreen non Entune in ( bought all the right adapters) and installed the rear view camera harness off of a member on eBay to show the view from the mirror to the touchscreen. All worked well until I got a deal on a 2014 Entune plus ( can't stop all the mods!)
Everything plugged in fine except the camera harness ( I believe is 16 pin) and the Entune plus is 24 pin. Does anyone know where to get an adapter or a schematic of the pin location ( I can make an adapter if left as my only option).
Thanks in advance

 

I would think a Toyota dealer could get you a copy of the schematic. Prob will end up making your own harness though.

 

Thanks for the respond back..... I believe it's only 2 wires so shouldn't be too difficult.... Just need to now which two pins
