Step 6: Install Into Project Box
Drill a small hole in the end of the project box so that you can run the wires out. After that, *carefully* run the red and black wires through the hole and add the opener, wires, relay, and capacitor / resistor pack to the box. It's a tight fit, but I was able to get it all in there snugly. Be careful not to break any of the wires or solder joints during this step (especially easy to do if using solid-core wire).
When done, add the cover to the project box and you are ready for installation in the motorcycle.
