Has anyone set up lighting that automatically come on when they shifting in reverse? Is there even a way to do so?

There's always a way. Sense the gear selector just provides a ground for the dash LEDs, one need only set up a ground-triggered relay. It would be as simple as this:

I thought of doing it that way, I am just scared that the leak through from the relay coil might cause issues with the ECU since it is a pretty direct source from the warning light🤷🏻‍♂️

Relay coil only pulls a few milliamps..like 0.03 so it won't. Hundreds have done it without issue. Advisable to use a keyed power source though.

I thought of the same thing so I bought an opto isolator to make sure.  My concern was that a voltage spike on the reverse sense line to the computer might potentially overload the input line.  A clamping diode on the relay coil would also offer some protection against a spike to the ECU.

I have a 2015 zforce 800 ex. I'm hooking up some revers light, but have no idea where to tap into the reverse trigger wire is located and or the color of wire to tap into. most of all, where is the reverse sensor switch located?

What you have to realize is that the gear selector switch only provides a ground for the lights in the dash. They have power all the time, just no ground and they are all on one switch on the back of the engine. What you want to do is use that ground wire for the reverse light as a ground trigger for a relay to send power to the reverse lights. It's easy...and its the only way you can do it. I think I ever have a wiring diagram with the wire color of the reverse light's ground to the selector switch. Yeah..here it is:
