3 Conductor

Connector Wiring: 3-Conductor

The purpose of this page is to share common wiring schemes for 3-conductor systems. As additional systems are added, please include them in a form in which others can benefit.

3C Water-proof connectors

Water-proof connectors are available from Ray Wu, but they can also be purchased from US-based resellers (ask around for names). The style has changed over time, so the chart also serves as a way to convert between old and new connector wire colors so that old and new connectors can be compatible as you add new devices to your display.
