OEM Foglight Wiring

[cavebloke]

Hi Guys,
I've got an import with a horrible aftermarket foglight switch on the transmission tunnel and a scruffy bit of DIY extra loom to link up the foglight hanging off the rear bumper. I want rid of it!

I'm going to do what many have and switch one of the reversing lights to a fog.

I recently got the OEM foglight switch from MX5parts which plugs nicely into the loom but can anyone tell me where I can find the foglight loom where it ends?
Presumably it's in the boot somewhere but I can't find it.

Thanks in advance,

Simon
