Hooked up the new boat trailer to my 4-pin connector and only the brake lights and turn signals work, no tailights or running lights. Anyone know which fuse # to check? I tried F29 (listed as trailer running lights in manual), but it looked perfectly fine.
Could this be a bigger issue than just a fuse? My 7-pin trailer connection works fine.
