The LED's are likely12v, give or take a little, so using the receiver as the power source is not an option. Most receivers have voltage limits of between 4.3v and 8v, +/- a little so you can't use that. Ideally, your MW will use a 3s battery, where the voltage is close enough to directly tap as the power source using an additional lead from the PDB. If your MR uses a 2s battery system a small additional battery would have to be carried to power the LED's or other items requiring 12v power. If the MR uses voltage higher than what a 3s system provides the installation of a small BEC would be needed to regulate the voltage downwards from a higher to lower level.
Since your LED's are already wired with JST connectors you have some power input plug options in front of you. Option 1 has all the JST connectors being removed in order to join the positive and negative wires together to make a single connection point. Meaning one group of negative wires and one group of positive wires, each ganged together in their own polarity with a single wire exiting each group to join up with a single connector. Option B is to make a wire connector set, where there are 4 outputs being provided from a single input source that connects to the primary power supply. Sort of like a "Y" but having two more legs on the "Y". Option C has you making a buss board that has a single "power in" but also having multiple pin outlets to plug different optional items into. Usually available space and weight end up making the decision as to which way an installation needs to be done. There's no on hard and fast rule that applies to this stuff, aside from a need to have some imagination and a reasonable amount of electrical assembly skills.
