Car wont start unless door is open

The connectors can't be swapped. Those bumpouts are different on each one.
The sevice manual drawing may be showing the view from the inside.

Alright. The bulkhead is normal. The diagram is as if you were looking down at it.
I measued a consistent 11.5 volts from the N connector. As well as the three endings of the run circuits.
However, when i was measuring resistance at the ballast, the upper right terminal and lower right terminal both gave me about 3.4 ohms.

This is different from what you said. If i uderstand correctly, the upper right terminal should have 5 ohms, and the lower right terminal should have 0.5 ohms?
Does this mean wrong ballast?
