New Guy Here. 2000 Silverado Alarm Questions

[Max463]

New person here who has some questions for more knowledgeable chevy owners out there.

 

I am attempting to install a regular alarm into my 2000 Silverado, on my alarm it only has (-) power lock and (-) unlock outputs. And I see that the car itself has both positive (+) power lock and unlock. Since I'm not installing a remote start to the vehicle, I didn't purchase any sort of bypass module for the passlock.

 

Do I need it to connect my alarm to my car?

Or do I convert the negative outputs to positive using relays?

 

Also since I was adding the aftermarket alarm anyway, I was thinking of running a line to back and attaching it to the trunk pin to act as a sort of door trigger for the tailgate. Can this be done the way I'm thinking of? I want the alarm to go off if someone opens my tailgate.

 

Sorry if I seem to be asking stupid questions. Thank you for your help.
