Question:

07 Pathfinder, tow ready, has worked great with your brake controller...just noticed I dont hear relay click when braking, and I have no power through tow harness...I have looked everywhere under dash for relay, even in the kick panels...could it be located behind ac knobs? Need some help before going to shop.

The online copy of the owner's manual didn't have the locations for the relay but based on some research it should be in the kick panels of your 2007 Nissan Pathfinder; we have not had a chance to install these on an '07 Pathfinder so I was unable to find the exact location; you should be able to call your Nissan dealer and ask them directly where the relays are that activate the tow package without it costing you any money.

I'm not completely clear about what you mean in regards to no power "through" your harness - which I assume you mean is the 7-way - but there are a couple troubleshooting steps you can take. Often, corrosion or dirt may be the cause of a short in a trailer connector so check the plug to see if there is any type of corrosion built up that may be hampering its functionality. Also check your wiring thoroughly to ensure there are none that are crimped, broken or otherwise damaged.

I have added links to a pair of help articles on trailer wiring, including a troubleshooting guide which I highly recommend taking a look at.
