Hi,

I have a 1998 Ford F-150

I just finished diagnosing a no Brake/Turn light condition on my boat trailer. The wiring was fine; so it's a fuse; right?

Well....reading the Truck's owner's manual...It described the location and purpose of all the fuses....but no mention of a fuse that overlooks the Brake?Turn circuits on trailer-tow wiring.

A search of the net turned up this page....

and the answer to the problem,. Ford had left out a page of the 1998 Owner's Manual; the very page that I needed.

As the picture shows...there is a THIRD fusebox...in the engine compartment by the Brake Booster that houses fuses for the trailer towing wiring.

Hope this helps someone....

Yep... Ford leaves a lot of things out of the owners manuals. I knew this, but only because I worked for Ford. ;)

Keep some extra fuses too... they blow pretty easy if you plug in your trailer lights while the truck is running with the lights on.
