All that's left to do now is connect the LED strips to the wires in the footwell...
...and then connect the other ends to the wires you added to the light (make sure to be aware of polarity).
Once all the wire is connected (and tested!) and the panels are all back in their place, just secure the strips in the footwell and hide the wiring. There's a small ridge in both sides that's perfect for tucking the lights behind, but it's up to you to experiment with where the lights point.
The red arrows here are pointless, I know.
I'll update the thread later once it gets dark to show how well they're working.
Hope this guide helped someone!
