Looks like this relay kit over on the Samba.com, has the fuse box
holder's, and it sure looks like they are factory VW relays.

All wired up, the wires are all marked and has the wire ties included
too.

Looks like a nice complete pre-assembled set up, and all this for  just
$37.00 ??

A guy could hardly beat this deal.
