Fog Light Power TO Switch Source - Fuse 41?

In the under-hood power distribution block, Fuse 41 is a 10-amp fuse that according to the fuse box diagram is for the "Automatic Transmission"

There is a fuse in it.

Since I have the MANUAL transmission, can I use that as a source of switched (ignition on) power to send as "Supply" to a switch in the cab for a set of additional fog lights?

The "Load" side of the switch will run to a 40-amp relay that will receive power from one of the main Positive lugs coming off the battery.

I suppose you could especially since you are only using it to drive a relay. Here is the diagram, and it only goes to the auto trans like you said.

That should work well. If you will be using LED fog lights? If so, they may not need a 40amp circuit. You could possibly use that circuit to power the lights also.

Do you already have a set of fog lights installed? Quite often, Ford has the wiring harnesses in place for optional fog lights. In that case, you can use the factory wiring. Just install the relay, connect a switch and connect the lights to the existing harnesses.
