Cables from Engine bay to Cabin.

Anyone got an easy way to get cables from under the bonnet to inside the cabin, I currently have an EGT and Boost Pressure sensor cable that I need to relocate (currently they come under the A 'Panel' trim and over the door seal).

I'd like to put them away properly but every time I get to looking for a 'way in' the to hell with that ****e muscle kicks in - do I really need to take off both A pillar trims and the wiper / windscreen lower trim to get at the appropriate locations.

I can't see where anything comes in from the engine bay to the inside of the cabin or I'd try pushing something through that I could get hold of. The entry that I found is the large one that comes in behind the fuse box and I'd rather not screw around with that.

I did use the one behind the fuse box, pushed a coat hanger through the rubber bung from the engine side, followed by a piece of string followed by the wire, seemed to work OK. I also looked at a friends V8 and looked liked there may have been a way in from the passenger side but I can't recall how, sorry.

There should be 3 holes with rubber bungs in from the engine bay into to cabin. One behind the fuse box one just behind the engine and one on the passenger side.

The one behind fuse box and the one on the passenger side is where all my new wiring get routed.
