Car Alarms: 2001 dodge durango alarm/ sentry lock system, dodge durango, car alarm

Question
What is the thing you have to install before you can install after market car alarm to a 2001 dodge durango with sentry locks? how do you know if one is already installed?

Answer
The "thing"?
If you mean "how do I install relays to make this door lock system compatible
with my after market alarm", you will need 2 relays and 2 sockets
& put in 2 resistors as this truck has a single wire door lock system.
This you would buy online or at a shop that carries 5 pin relays.
