Problem... grand caravan, ungo sr5000

I had the ungosr5000 alarm installed in my van from a friend. But cant get a hold of him. A resistor broke and the parking lights dont flash anymore. Can somone redo the one for me?? How much and when. Plus i need a shock sensor where can i buy one. Right now all i can do is start it. And lock it. You can bang on the car doesnt do shit. And the alarm siren isnt the original and you barely can hear it anyone have a loud one in there shop??
