For starters, you will need to make sure the proper relays are installed on your 2010 Nissan Titan. To check this, you will need to gain access to the relay panel located under the hood near the battery. Once you remove the panel cover you will need to check for relays in the following positions: trailer turn rh, trailer turn lh, and trailer tow no. 2 (see photo). If you can confirm that you have these relays and they are in working order, then you can begin to check the wiring. If you do not have these relays or suspect they may be bad, then you can acquire them using part # C57000.

If the relays do not fix the problem, then you will need to begin checking the running light wire for power using a circuit tester like part # PTW2993 at intermittent points until the break in the connection presents itself.
