    Hi all. I am trying to install auxiliary LED reverse light pods onto my 2015 Tundra Platinum. I want them triggered by a switch and by the reverse camera. I have the switch part worked out. Where I am having trouble is figuring out which wire to tap into on the back up camera back by the tailgate. I located the wire bundle/connections under the rear bumper. It has 4 wires. The black wire looks to be always hot at 6v (in park and reverse at least). I am not detecting any voltages at any of the other 3 wires when in reverse. Can someone please provide clarity as to what wire I should be tapping into? Thank you.

    Why not just go straight to your reverse light and pull the positive to trigger a relay harness for the lights? Cameras are typically 5-6v so they aren’t going to work as a suitable trigger.

    Thx for the reply. I had read somewhere (I think it was on this forum) that the preferred method was to tap into the camera hot line (fed to a relay). That way, no diode is needed to prevent backfeed to the reverse lights when using the switch (and the truck thinking that I’m in reverse if I’m not) and the camera will kick on when I activate the lights via the switch (and not necessarily being in reverse).

    You will not back feed when using a relay. Danman’s method is the correct and standard way of wiring in lights. The reverse light wire just acts like power from a switch .

    Thanks for your input. I was trying to keep this high level, but probably need to get into more detail. I have one of these installed that I will be using as the switch. https://www.amazon.com/Blazer-C3050K-Wireless-Management-Accessories/dp/B06XNV3PPC. The output from one of the sets of ports will go to the relay pin 86 for the switch on/off functionality. I also want the lights to turn on while in reverse, so I was thinking the the reverse light wire (or my original thought of the backup camera power) would also be connected to pin 86 of the same relay. This would put the 2 connections into pin 86 in parallel, which is why I was thinking I would have a backfeed issue when using the switch. Is that not the case?

    I would also like the backup camera switch on when I use the switch (while not in reverse). Is there a way that this can be done?

    Thanks again for your help/feedback.
