If the cable is correctly attached to ground and to the harness under the steering wheel.

Then the only two things to check would be the 15A fuse under the steering wheel area, and that the relay is connected in the right place very close to where you checked the fuse.

Then to confirm, I would use a voltmeter/multimeter, and put the red to either of the two pins in the fuse box in the engine bay as pictured, and the black(ground) to the battery ground.

Then flip the switch to the on position on the fog light switch and check the voltmeter to see if power is being sent to those two pins in the engine bay fuse box.

If you see power, then something is wrong with the fog light wires.

If no power, then something is up with your inside wires or fog light switch.

Get back to us with this. Also does the fog light indicator light up on the dashw hen you turn it on?
