For the keyless entry problem. How many out put wires does the alarm have for the keyless entry. There are probally 3 out put wires for the 3 different ways you can hook it up. When i did my alarm in my civic you just use the basic unlock/lock. Read in the manual and you want to use only 2 of those wires. One of the wires from the alarm is going to provide a negative pulse during arming, that wire be connected to the wire in your keyless entry which locks the doors. The other wire from your alarm is going to provide a negative pulse during disarming, this will be connected to your wire in your keyless entry which unlocks your doors. Also with the alarm, when you hit the disarm and it unlocks the doors, it unlocks all your doors. With the factory keyless entry you had to hit it twice to unlock all doors.

My alarm had 3 wires coming off of it, a red, green, and red/black wires for the keyless entry. Red was lock, and green was unlock and the 3rd wire you dont use.

And for the truck release you need to use a relay or you will burn up your alarm.
