Help Firing Dad's Dart up Again - SOS - No Spark After Hosing Off the Dust
Not sure if you need this now, but in case you do.
Both of the striped wires are used to power the 5 pin ECU.
The 5 ohm resistor reduces the voltage and therefore power draw of the 5 pin ECU.
Four pin ECUs have an internal power regulation so don't need this. They should work on a 5 Pin harness, they just don't use the red/green wire.
In Start, power from the key switch comes from one of those brown wires. The other one provides power to the coil. No resistance is used because voltage during cranking is supplied at less than 11 Volts vs. over 13.5 when running.

It shares the power coming from the run circuit. In run, the half ohm resistor feeds the coil and the five ohm resistor feeds the ECU.
