SWI-ECL2 - Pacific Accessory Corporation Steering wheel control interface for Eclipse

You want to install an Eclipse stereo in your vehicle, but you hate to give up the convenience of your factory steering wheel radio controls? No problem. PAC's SWI-ECL interface allows you to use the steering wheel controls in a wide variety of vehicles to command select Eclipse radios.
Installation is straightforward  just connect a few wires, only 3 wires in many cars. The direct connection to the stereo means there's no need for an infrared emitter, allowing the SWI-ECL to function even in bright sunlight. Step-by-step LED confirmation makes programming easy. Once connected, the SWI-ECL's failsafe memory will learn up to 5 stereo functions, retaining them even if battery power is interrupted. Dimensions: 3-3/4"W x 1-1/16"H x 1-9/16"D.
