26. Now, to test an actual switch! With our taillights still on, we connected a standard 12-volt test light to our light green CHMSL wire that had been routed into the trunk lid. A quick application of the brake pedal shows the LED brake lights illuminated, as well as our CHMSL (which is also LED, but not installed at this time). We’re looking forward to hooking up the rest of our ISIS system as we move forward with our dash switches, gauges, and lighting.
