Where to run a power cable in the 197?

[mattg]

I've just picked up my R27 on Thursday and want to swap my audio across from my 182. I can't for life of me see an obvious way of getting a power cable or two through to the battery, dispite reading through all the posts on here.

Can anyone enlighten me with a how to? I've tried the get through the large grommet in the passenger footwell but with no luck. Any help would be much appreciated!

Thanks, Matt
