Going back to stock would be easier than moving to another aftermarket integrated taillight unit. It isn’t plug and play for aftermarket integrated taillight you have to splice wires.

 

What I'm saying is MAKE it plug-n-play. Do it exact same way factory does. Get 2x 2-way connectors for turn signals and 3x pin-terminals for brake/tail light. Crimp & solder terminals onto wire-ends and click them into connectors. Done!

Exactly like how factory lights are terminated and you just plug directly into factory harness after unplugging factory lights. No need to hack up harness, creating shorts and blowing fuses. Will work perfectly 1st time around because you did it exactly like Honda factory. But instead of plugging in factory turn signals and tailight on assembly line, you plug in the integrated taillight of your own choosing. No splicing wires necessary.

Or if you don't want to make your turn-signals/tail-lights plug-n-play, you can get adapter-harness to fit your aftermarket LED light's bullet-connectors to factory harness connector:
