If your horn honks on second lock press of remote you have a factory security. If you would like to test it do this...
roll down drivers window....press lock twice on remote..wait about a minute...open the door by reaching thru the window and manually unlocking..the horn will honk..lights should flash..to disarm...press unlock or put the key in the door and turn to unlock it. That simple.
I list nothing about waking up the GEM on your particular truck regardless..but this is how you should do the door triggers. Instead of going to all the wires..use the domelight supervision wire of the truck and connect it to the positve door trigger input of the system..usually a violet wire. The trigger stays on for a while sometimes after the door is closed (delay) so if your system can be programmed to ignore the delay (all dei's can be as well) it will save time and you won't have to diode everything. And correct..on this truck you can't tie the factory security to the aftermarket so either carry 2 remotes or forget the factory..its pretty useless IMO anyhow.
Heres the wiring for everything to do an alarm and remote start for your truck. Good Luck
