Fog lamp problem

[04Edge3.0]

2004 Ranger Edge 3.0 4x4. My fog lamps only work if I use a paperclip to jump the wide connectors in the relay under the hood. The relay is not getting power to the narrow connectors. The fog lamp fuse a couple of inches away has power on the hot side of the socket. There is no connectivity between the neutral side of the fuse socket and what should be the hot side of the relay (narrow connector). I thought of just running a braided wire between them in the fuse box and use the fuse and relay to hold it in place, but would I would rather fix it right. Anyone have any any suggestions of what to check next?

If the fuse has power have you tried just changing the fuse?

No, but I checked the fuse with an ohm meter and it shows no resistance.

I tried another fuse. No light.

Likely the wire from the fuse to the relay is bad.

On my 02 when you turn on the high beams the fog lights turn off. It could be that relay.

The light switch, ignition key, and fog lamp switch only open or close the ground. I have checked those on the switched terminal on the relay with a multi-meter and they seem to be working correctly by opening and closing the ground.
From another post on this site I found a diagram that shows that the live input to the relay is just a simple light green/yellow wire from the neutral end of the fuse. Getting at that wire from the bottom appears messy. The battery junction box is closed on the bottom, so I can't see anything with a mirror. Maybe a simple jumper from the neutral (unpowered) terminal of the fuse to the input terminal of the relay is worth a try.

got fog lamps working

I was mistaken. By studying a wiring diagram, I found out that the fog lamp switch does indeed only complete the ground circuit, but the power to trigger the relay does not come through the fog lamp fuse under the hood. It comes from the fuse panel inside the cab, and must receive a signal from the light switch and the ignition key to provide power to the relay trigger. The previous owner of my Ranger installed a remote starter, and probably messed up the signal wire from the ignition, so I decided to provide power to my relay from another source. I used short jumper wires from the relay to its socket except I provided power from the radio fuse to the triggering hot terminal. The relay hangs by these jumper wires. Now the fog lights work when the fog switch is on and the key is on.
