I was able to reuse my usb port and connect to to my Pioneer headunit. I took an old usb cord and cut off the end, and stripped back the leads/insulation. I used a multimeter to figure out which lead to connect to the Toyota USB jack (after cutting those cables), soldered the connections and followed up with heat shrink. Works fine.

The aux desn't work, I didn't have a good place to connect it on back of the headunit.
