Hi, my buddy bought some of these a while back and asked me to help him fit them yesterday: problem one is that he lost the wiring instructions. . . . However, there is only two wires that need figuring out, and they are the ones tha connect into the connector block at the back of the light switch. I googled various things and watched YouTube videos and the general consensus was that what I’m assuming is the the permanent power feed (fused blue cable) should be connected to pin 15 and what I am assuming is the the switch cable (black unfused) should be connected to pin 8. However, this doesn’t work. Using a multimeter and trial and error, it works if the perm feed is connected to pin 8 and the switch feed connected to 10. What’s doing my head in is that if you stick a multimeter on pin 10 there doesn’t seem to be any voltage change when turning the fog light switch on or off, yet it works perfectly.

Any thoughts?
