WIRING:
Connect temperature sensor wires to control box. (For more details see STEP 7: WIRE TEMP SENSORS)
Plug the 5 pin connector of the Display Harness into the display. Route the other end of the cable to the
DCC-control box and plug it into the control box connector labeled “DISPLAY CONNECTOR.”
Connect the 14 pin connector of the DCC controller harness to the connector labeled “GEN-IV
CONNECTOR”.
Route the DCC controller harness to the GEN-IV module.
Connect the 12 pin wire connector to the 12 pin connector on the GEN-IV module.
Connect the 16 pin wire connector to the 16 pin main wiring harness connector on the GEN-IV.
Connect the GEN-IV harness into the remaining 16 pin connector on the DCC controller harness.
(optional*) Using the HLC harness (2 six pin connectors) connect to either one of the 6 pin connectors on
the DCC-4000 display. Connect the other end to the “CLOCK CABLE” port on HDX or RTX control box.
(optional*) If the HDX / RTX system has an analog clock, connect its HLC harness to the remaining 6 pin
connector on the back of the DCC-4000 display.
If not already wired, wire the GEN-IV wiring harness as described in the GEN-IV manual.
*Optional connections for HDX/RTX theme matching. See NIGHT TIME DIMMING AND THEMES on page 7.
