This appears too come up on the forum quite a bit. So I have tried to devise a simple guide with a few photos to help explain.
Power Cable to Battery Guide 98 Onwards
Locate the bonnet release cable grommet in the foot well on the passenger side of your car.
It will look like the picture below; if you can’t fit it then give up now because you’re too stupid to even start this simple task J

You heed to make a hole through this grommet without piecing any of the other cables. Past experiences suggest that a wire coat hanger is the best tool to use but a screw driver will also do the job.
You now need to locate this grommet from the engine bay. The first step is removing the coolant reservoir (circled below). There are 2 bolts, undo them and remove them without dropping them!!

Removing this should give you the freedom to get behind the sound proofing.

Your going to need to force your hand behind this.... so dont be sunch a girl!! Unless you are a girl in which case ask your bloke to do it Its worth a few scratched up the arm
The grommet is approx 1ft across to the right 15 inches down.

Your need to feed the cable through here. Again the best tool is a metal coat hanger with a loop on the end. However you can also tape the cable to a screwdriver. Pull the cable through. Be warned its tough!!
Thats the last step it should look something like this...
