Car wont start unless door is open

welp. We did some more consolidating and fixing things. now the car starts and stays running.



......If the passanger door is closed. I am under the impression this is somehow a safety feature and that people arent aware of it because not many people start their cars with the door open...

Moving on from this problem now. Any ideas where the fender mounted turn signals plug in? I dont see any place to plug in on the turn signals or anywhere.
