I had to move some pins when I installed my Pioneer HU with the METRA harness. I used some small screwdrivers to release the prongs on the pins, a real PITA. You might try this tool:

A google search shows lots of info on removing pins. As far as the other wire, not sure about that. I reconnected everything when I moved the CDR-220. Glad you like it though!
