as a few ford modders said that you could get the wiring through the clutch cable hole next to the booster,as i had a look i realised that there was wires already coming out of most holes...
as i have lpg were can i get the wiring through to the engine bay or do i have to drill a new hole?

What size cabling are you using? The way i did it is ran it through the same hole as the bonnet release cable
