I am going to run power to the rear of the truck and want to run it from the HAPP then through a relay that I will connect to an aux switch. I have a 2023 3500 with a 6.4. I am looking for a place to mount the relay and am not seeing any obvious area in the engine compartment. I have seen a few posts about others who have installed power through a relay but not seen any photos of where they put the relay. I am considering putting the relay on the frame rail just past the engine compartment. If anyone has a photo of where they found a spot for the relay it would be appreciated.
