Just get a reverse wiring harness. That way you won't screw it up.
Thanks for replying. I have this connector and I try the black (Ground) and Blue (ACC) wires, but it's still not working (turn on). Am I missing some connection?

Probably. Hopefully you didn't smoke it.

Since you have the connector, go on Metra's website to see which pins do what.
