Hi Mike,
Both the loom from the fuse box and the grommet that goes through the firewall sit above the pedal box.
Except when it runs along the bottom ledge of the dash where the back of the pedal box bolts up, it goes underneath it.
Really hard to get a photo of it through the tacho hole as there is so much going on in there. If you need a pic, I’ll try and take one.
Hope these help, if not let me know?
Doug
