2002 trailblazer doorlocks

well i gave it my best shot but its winning.............the only thing the wife wants is keyless enter

2002 chevy trailblazer did not come with factory alarm or keyless enter

installing:

galaxy 5000rs

omega db-gmdl-bp

so far after 7 hours of hot sun and 12 cases of beer i got this far.....remotes and alarm works fine

remote start works great ......thought that would be the hard part

just cant get them darn doors to lock or unlock........sorry honey im triying..........i can here the clicks in the galaxy when i hit the remote to lock/unlock

i ran the wires from the galaxz (green wire lock output and blue wire unlock output) to the omegas inputs ....does the omega send a signal to the odbdII to lock/unlock the doors? or am i missing some other connection or wires? programming? do i need to do something in the doors..thanks for any help
