[2005 PF adding trailer electric brake capability]

I just looked it up, the 2005 Pathfinder like the Frontier, Armada, and I suspect the Xterra, is pre wired for a 7 pole trailer connect. That includes the brakes. You can go to your local dealership and get the trailer wiring kit that is all plug and play. It comes with everything but the brake controller, but it does have the pigtail to plug into the harness under the dash to connect your controller to. It also has the needed fuses and relays for the system. There is a flat 4 kit also, but you were wanting to have the brake system, so the 7 pole round plug is the one you want.

 

I spent 2016-2019 at my local Nissan dealership and did hitch installs among other things there and knew the newer stuff was prewired, just was not sure how far back they were. 

 

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.

Hope this helps!

[Rear brake suggestions]

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.

[new R51 4x4 owner]

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.
