Wiring the components: part 3 (Test circuit and final wiring)
Now we will wire the test circuit, which will be pretty straightforward.

Cut 8 short jumpers out of black hookup wire, stripping 1/4" off of each end, and solder them between the positive leads of the green LEDs in each column. Connect the first two columns together and the second two columns together using a longer jumper along the bottom of the columns. Then use jumpers to connect each half of the channels to the lower, unused tab on the toggle switch. This is the same arrangement as the armed circuit.

The last thing to wire is the positive connection to the battery. This will go directly from the fuseholder to a quick connect terminal and then to the battery, since everything past the fuseholder is already wired and ready to go.
