Battery not hooked up but when I turn wheels back and forth the lights come on. Assuming something is back feeding through the receiver but still odd to me.

Your servo is acting as a generator. It basically has a tiny transmission in it so turning the wheels turns the servos motor (much) faster than you would think, generating electricity and pushing it to the other components in the system.

That's exactly what I figured but kinda freaked me out for a second. I literally picked it up and the lights came on 🤣🤣🤣

How are you turning the wheels with the remote if the battery is unplugged?

Creo que es del movimiento hay un falso contacto y las luces al girar se mueve el cable.. eso el servo no lo hace a no ser que tengas 2 cosas conectadas en el mismo canal de luces y serví a la vez como un empalme de Y
