HELP please! Center diff light flashing

[micahmr2]

So I finally got around to fixing my actuator leak on my 2004 V8 sport. I followed the procedure here, http://www.toyota-4runner.org/4th-gen-t4rs/182074-fixing-transfer-case-shift-motor-leak-within.html, after turning the key on I get a center diff light flashing. I vehicle moves normal in HI unlocked, but can't engage 4lo or lock center diff. I don't believe I changed anything when I pulled the actuator out. Any thoughts. Can I scan it with an OBD scanner to get codes?

It appears there is a small wire broken at the plug. Now I need to figure out how to remove the pin. Any help?
