This was a pain on my latest project. I put an older pioneer touchscreen in my girlfriends 2008 escape. There is no longer a switched +12v going to the stock radio. There is a fuse box on the passenger side by your feet that has wires going in and out. The wire I ended up using was yellow I believe and went up out of one of the wiring harness. Sorry I don't have any pics, I didn't have my camera when I installed it.
