So you do have aftermarket electronics. Oh yes, these can definitely cause issues and draw power, especially if they also have LED reverse lights with incorrect wiring or resistance (I'm assuming you have a US spec Camaro where the reverse lamp is in the taillight assembly and not at the bottom center, Mustang style, like it's done on EU/Asia Camaro models).
If you can, check in the dark if the reverse lights are very dimly lit even with the car off.
Then, if you don't see any unwanted light output, take out the multimeter and measure power draw around the taillight connectors. Unlike bishopts, I'm not a mechanic, so I don't know the exact ideal amount, but a couple milliamps should be okay, while a couple hundred milliamps would definitely deplete your battery fairly quickly.
Also if you still have your OEM taillights, you can swap them back temporarily for an A/B test.
