This could be caused by many things, but most commonly this is caused by a short on the running light wire.

However, since you did your own wiring with a diode kit, I recommend checking that all of your wiring that you did is wired correctly with your factory harness.

You're also going to want to check your ground connections, and ensure that none of your wiring is backwards.
Finally, this also could be caused by corrosion inside the trailer connector, so I also recommend checking into that as well.

If you're still having issues feel free to come back and I'd be happy to assist you further.
