Nice idea Richard, not a major job to wire in a couple of booster points, all you need is a feed spur off the starter motor main feed lead and an earth point, you could probably buy an insulated feed post from somewhere like car builder solutions and have both mounted a few inches apart on a plate under the bonnets? Only an hours work for a garage at the most and about £5 - £10 worth of materials I guess. I put something the same on my 2002 +8 when I moved the battery from the front to the rear axle.
