I've mentioned this accessory  more than once and the headlight relay
thread reminded me to do it again.

Next time your at the wreckers, pick up one of those small fuse
"panels" found on later model golf/beetles (2000- 2004?) . They are
attached to the battery and you often find them just hanging in space
after the battery has been removed. I think I paid less than 20 bucks
for mine.

They have a short pigtail of 4 gage (a guess) wire that connects to
the pos. terminal of the battery, but this can be adapted to suit.
Its has 4 fusible links (2 X 110 A, 2 X 50 A) and 3 spade fuses.
