Joining wires

And another thing to do, use some large white or yellow heat shrink on the the wires before you put the connectors on for the switches and lable what the wires go to.

If you ever have to take it all apart again it will save you so much time, and it looks more professional for the IVA.

Also raid a scrap yard for VW wiring tubing and T's, also looks very professional in the engine bay, particularly if you are going EFI.
