Important Note About EIS Warning Lights: We have recently starting shipping LED warning lights with attached wires. The violet warning light wire is no longer present in EIS wiring harnesses, as shown in our wiring diagrams. The new LED warning lights have a D-sub terminal pin already attached to one of the wires. This pin can be snapped into the D-sub connector, pin 7. The other wire must be connected to +12V power. We will be updating the wiring diagrams at a future date.
