I have a 2009 Maxima which I installed toe forin combo 5 Evo Nist 1. I followed along a youtube video. I installed the unit. The only wire I had to tap into is the keyport brown wire using the white black wire, plus obviously the harnesses. The starter works. When I initially installed it, it seemed to work fine. THe lights worked on the unit as they are supposed to. When I put pannel back on and opened the door there was a rapid clicking I couldn't tell if it was the starter or a relay, but it seemed to drain the battery quickly. I took it out thinking there was an exposed wire. I didn't see anything but added extra tape on everything repositioned the unit. Put it back together seemed fine until the next day I opened the door and the same thing happened. Any thoughts?
