classic or nnbs?

I will find you the info tommorow. nnbs 07+ dont have a fuse. There is a wire you connect with a nut in the fuse block.

there are two wires to hook up when installing a brake controler both are under the hood. remove the fuse box cover and there are two studs at the front fuse box. there are two wires with eyelits criped on the them they are tapped to other wireing harness on each side of the fuse box. one wire is for the brake controler and the other is to charge the battery of your trailer it goes right back to the trailer plug. for that one you will have to intall a 40A fuse in the correct location in the fuse box. connect both wires to the correct stud and you will have no problem.

happy towing.

as always if you have any concerns stop and ask you local dealer. they should be happy to help.

I hate to highjack, but, I am doing the same thing right now. What size are the nuts that are needed to install those wires on the posts. I know that they are metric.
