If wired correctly, using a relay triggered by the reverse line to turn off the license plate lights does not affect system operation. There appears to be enough leeway in the Running Lights circuit that temporarily turning off the two license plate LED lights does not raise any system monitoring issues. The (very minor) added draw of the relay also appears to have no effect on the reverse circuit.Exactly - @ShadowsPapa provided a good reason not to - it could compromise the reverse function. Either technique could be used and not compromise the oem wiring by using the modified harness, but using pins 5 & 6 energizes the relay while keeping the reverse circuit unchanged.
If it is really a concern, you can use a T harness available from Curt to tap into the towing wires to activate the relay. I use this method to operate my added backup lights from the reverse line. They have been in use for over four years with no issues. The lights are connected directly to the Reverse line and ground wire in the towing circuit (like a trailer would be).
