We often get this question:
"I'm interested in purchasing the red strip LED tail lighting for my 2019 ND-2 but need to know if it's compatible with the FM Sequential LED rear turn signals that I already have installed in my car? Would its addition overload the circuit causing the fuse to trip? "
It is fine to plug one harness to another, it will not affect tail lights, because all the wires going straight from one connector to another. Power consumption of LED strip way below the tripping point of the tail lights fuse.
