I like biscuits and mustard.
 
There's an ARINC232 cable under the dash. Just unplug the green wire with the stripe on it and plug your USB2 adapter into that jack. You can get a hot power supply by tapping into the right engine fire bottle power line. It's on the Hot Battery buss so it even works when all A/C power is off.

Please be very careful... the ARINC232 cable is a orange/white striped cable, and DO NOT splice into the cable marked "BTB002A", which is baby blue in color. Cutting into cable especially in flight, causes for a lotta chit to go wrong. You do NOT what to have to write that up, or explain why it was cut.

My personal recommendation is to go through the overhead panel... unlock, and fold down. Look at the bundle that is near the ignition switches.... This is tricky - to get PSP on any MFD, or multiple if you want crossover viewing/control, you need to cross wire the L/R start switches. Just remember to switch it back when you done.
 
Its easier if you raise the hinged cover on the maintenance panel behind the captains seat, and plug in there. Feel free to tweak the potentiometers that are close to increase the bass and volume on the intercom too.
