This plan view shows the tool used to remove the brass connector from the plastic housing. The blade of the tool measures 1mm wide X 0.5mm thick, and the tang of the brass connector rises on the same side of the brass connector as the fold over "crimp ears" rise from.

This side elevation shows how the tool engages the brass tang to depress it down to clear the plastic housing.
One can also file a finish nail to a square point and relieve one side of the nail down to the thickness and it does work. with the tool/nail there is no need to cut any wires. Once removed from the plastic housing, cover the exposed brass connector/s to prevent it/them from CONTACTING GROUND with some heat shrink tubing and a couple of wraps of electrical tape.
I can not explain the workings of the RLM circuitry but the modification/s I list above should help extinguish that pesky, annoying RLM indicator bulb.
