I bought a avital 4105l remote start kit to put in my Durango I have everything hooked up.I think I have all of it in the right spot but the only thing it will do is flash the light for a minute when I press the lock button does anyone know anything about installing them it’s the 5.9 v8 with the black key

 

Does the manufacturer of your remote start have a tech line???

 

they do but I called and they said they can’t help because I’m not one of there professional installers

 

Well, that's helpful.....

What year is your Durango, can you post the wiring diagrams for the remote start?
