Question:

This is the the kit that Im using, #C55242, is a plug and play and comes with two relays, and I found out where they are used on my 2003 F150 4x4 crew cab short box with electric trailer brakes and uses the 5.4 engine in it along with the origional Factory tow package on it. But it also comes with two green 30 amp Maxi Fuses and I have NO IDEA where the two Maxi Fuses are used on my F150?? Can you please help me? I looked in the owners manual and can not find any Maxi Fuses used. any help would be appreciated. 11/29/2021

According to the installation instructions for the Curt T-Connector Vehicle Wiring Harness # C55242, the 30 amp maxi-fuses go in the Trailer Tow Electric Brake and Trailer Tow Battery Charge locations. These fuses are located under the hood in the power distribution fuse box. 101 is the Trailer Tow Battery Charge fuse and 108 is the Trailer Tow Electric Brake fuse.
