One thing to be aware is that the Germans seem to wire using the following plan:

power > switch > fuse > load.

as opposed to most others which is:

power > fuse > switch > load.

This results in a totally different way of wiring that the pre made looms like painless do not address adequately unless you totally replace all the wiring. Also, this will mean that, most likely, any electrical issues in the future will need to be addressed by you or a mechanic that is willing to work with a non-factory setup (most are reluctant).
