i just bought an oem titan hitch with out the relays and the adaptor that connects to the hitch itself. i bought the adaptor from the dealer and also bought a relay switch. i know my 2004 needs two relays one for the trailer lights and one for electric trailor brakes. i don't have a trailor with trailor breaks so i only need the relay for the trailor lights. so my question to you guys is what is the model number and the color of the relay for the trailor lights? the dealer sold me the a brown relay which connects to the trailor tow 2. did they give me the wrong relay?
