7 blade trailer plugs and relays
I hav a 2009 Pathfinder. I am removing an OEM 4 pin trailer plug and replacing with an OEM 7 blade trailer plug. Do I need any relays? If so which ones? Any help would be appreciated. Thank you!

They should already be installed if you had a factory 4 pin

You'll likely need the trailer relay, P/N 25230-7996A.

Thank you for this link, I was given this set of instructions when I bought the harness. I don’t see any relays mentioned. However when I look at several other installation videos on the web using etrailer and other brands of harnesses they supply relays that need to be installed. It makes me wonder if they will be needed for an OEM harness since it wasn’t a factory installation.

Everything plugged in flawlessly. The harness is installed and the relay has been installed. All blades are getting DC except the electric brake blade. Any ideas about what might be wrong or missing would be very much appreciated.

I installed the OEM plug harness, which matched perfectly to factory plugs on vehicle. Tested plug and had DC to lights, but not to trailer brake blade. In the small relay box which held 3 relays there was one relay in the trailer #1 slot. Trailer #2 relay was missing and a pump relay was also missing. Installed the trailer #2 relay then tested the plug blade for trailer brake still no DC. Checked all fuses listed as trailer fuses and they were good. Do you have any suggestions about troubleshooting this problem. Thank you for your help.
