Pulled this from my GMC Sierra. Its an older DEI, ~2004. Brain is an Avital Avistart 4200. It also has the GM security module (555L?). All wiring is there and its all together as 1 big bird's nest. Nothing is hacked up though. 1 remote. No manuals. I did write wire locations & colors in case you happen to have a similar truck. Worked perfectly fine when installed.

You can try to get manuals here (both will require registering and/or product info):
