I have done this to my 08 R51. The wiring harness from Nissan will not work. You need to convert the 4 pin to a 7 pin plug. There is a kit on etrailer.com to do this. There is also a video on etrailer.com that shows you step by step how to connect the harness. The kit from etrailer will give the option to have both 4 pin and 7 pin plugs. The brake controller will also need 2 relays (also found on etrailer) to function. I tow a 19ft travel trailer with a brake controller and also a utility trailer that is a 4 pin for hauling wood etc. Here is the video of the install. It also should have the part descriptions/numbers in the video aswell. https://www.etrailer.com/tv-install-brake-controller-2011-nissan-pathfinder-39510.aspx Hope this helps!

I get all my brake stuff from https://www.r1concepts.com/ they have great products. I have their drilled/slotted rotors and pads on my MBZ, Honda CRV, and wife's 4runner. I will be replacing my R51 brakes with their components as well when the time comes.

Hello everyone! I just purchased a 2008 R51 4x4 S. It has 90K miles and runs great. Since I bought it I have been reading about the common transmission problems with this generation Pathy, so I am aware of the option to bypass the radiator cooler. I did purchase the truck with a full warranty. That being said, I am a little reluctant to bypass the radiator cooler and just run the factory external cooler because I don't want to void the warranty the truck came with. So, my question is... Is there an aftermarket radiator I can switch the factory one with to remedy future failure from the factory radiator leaking? Or do I just let it go and if it fails just repair it under warranty, because it would definitely be covered. I have checked the tranny fluid and coolant often, and so far have not found any signs of the 2 fluids mixing. The truck runs awesome, shifts great, and has plenty of power, so I don't really want to let it fail. I just want to get everyone else's input. Thanks in advance, and i'll have pics up as soon as I can take some nice ones out in the dirt or snow.
