Hey guys i have an plx alarm system and a few days ago i tried to hook up an automatic hatch opener so that when i pushed the button on my fob it would open, problem is when u brought the car the wire for that was cut fully off. So anyways i put everything back together and didnt hook up the automatic hatch and put everything back. I noticed one thing yhat really bothered me. My alarm system usually would flash my parking lights or my lights all around my car when i locked it or opened it. Now it doesnt. But sometimes it does. Can anyone give me some info on what i might need to do. Its not to major but it is yes very distracting. Its just something i need to have done. Thanks guys! I can send you a picture if then alarm systems harness if you need.
