Car wont start unless door is open
You are holding the Run Circuit. The wires are labled J2 and then a branch letter. This is also called the ignition circuit, or ignition run circuit.
from the Dodge Chassis manual page 164
J2 is cavity N middle connector. Use the bumps (green arrows) to figure out the orientation. If its too difficult to access go to an easier junction first.
16 is wire size, DBL* is dark blue with stripe.
It looks like someone got black spray paint on some of the exposed wires but you'll figure it out.
Lets give these wires their ID and what they do.
The dark blue is J2A, a branch of the Run circuit.
Dark Brown J3 connects to the coil positive. It must be connected to the 0.5 Ohm resistor. With the key off, measure the ohms accross that resistor. If its 5 ohms, its the wrong resistor.
The light blue with yellow, and the green with red wires go to the ECU. The Green with Red (J4) must be connected to the 5 ohm resistor. With the key off, measure the ohms of that resistor. On newer ECUs that wire isn't needed, but since its there you can use an older module or an newer one.
A light blue wire with yellow strip should be J2E, RUN power feed to the ECU.
