There is a separate fuse for the trailer turn signal/stop light connector, and a relay. Check your owner's manual.
If you don't have an owner's manual, you can download one here.

Not on an '04 Powerstroke, no. There are no fuses under the hood. The trailer tow stop/turn fuse is #6 in the CJB under the dash. Parking/running lights is #38, backup light is #39, 12v power is #115.
The stop/turn relays are in Auxiliary Relay Box #5, which is under the hood. The parking/running, backup and 12v power relays are in the CJB.
