1975 Plymouth duster brake relay question?

In the 1975 model year, there were two engine wiring harnesses.
Chrysler part #3843129 was used up to 10-14-74 and it had the interlock system.
Chrysler part #3843461 was used after 10-14-74 and did not have the interlock system. That was the reason for asking for the build date of the car.
There are 3 steps to permanently disable the system.
1. Reach under the seat and unplug the sensor.
2. Unplug the green or blue interlock module under the dash.
3. Splice together the two yellow wires going to the interlock relay under the hood.
If you don't want to cut and splice the yellow wires you can make a jumper cable. Take a 12 gauge yellow wire and crimp a male terminal on both ends, then plug the jumper cable into the interlock connector plug. This connects the yellow wires together instead of cut and splice.

I pulled the bulkhead connector from the dash side and swapped the 2 yellow wires in it to bypass mine. This effectively connects the starter switch directly to the starter relay. The OEM wiring has the yellow wire split and go to the interlock module under the dash and through the bulkhead connector to the emergency start relay next to the power brake booster, resulting in no direct connection to the starter relay. There is in addition yellow wire from the interlock module through the bulkhead connector to the starter relay. So by swapping the yellow wires in the bulkhead connector, it looks completely stock but there is absolutely no way the module can cut the starter circuit.

I believe the wires could be swapped in the engine side harness as well. I had my dash harness out so I did it there while I was dinking with other changes.
