Gents

I have just acquired a 288Watt LED light bar for my Disco 3... at approx 43" from mount to mount it is too long for the bull bar so i am looking to mount it on the roof.

My question is, what is the easiest way from the roof to under the bonnet on a D3 without putting extra holes in the panel work? I was thinking about running it down the "A" pillar behind the black cover (if I can work out how to get it off) but it only takes me behind the front guard and I can't see anyway from there into the engine bay.

Any suggestions or routes others have used would be most welcome...
