Alarm/ Starter 2002 Neon

Hi all, recently put a Compusar alarm/starter combo in my '02 Neon. After the initial install I had a problem with the alarm falsing after remote start. The door pin wires would drop voltage, about 4-5 volts with the park light flash and this would set the unit off. To combat this I used the doorpin wire to trigger a relay instead getting rid of the problem, but.........

Now my dash lights do not work unless I open the door

Wondering if anyone had some thoughts before I get into it again.
