These instructions only cover the electronics, the assembly of the actual housings is not shown here.
The end result is this:
Please read over this guide before starting to follow the instructions as there is some ambiguity sprinkled in throughout the steps.
I've included a complete wiring diagram just in case my instructions don't make sense.
