INSTALLATION INSTRUCTIONS FOR FRONT MOUNT DUAL CONTROL UNITS

The Dual Control Unit feature is configured such that only one control unit can be used for Extended Option accessories. All Extended Option accessories are connected through the Main Control Unit.

1.Referring to Figure 33, run the Dual Control Cable (19B802554P9) between locations for the Radio Unit and Auxiliary Control Unit. Be sure to locate the P2/P3 connector assembly at the Radio Unit.

2.After installing Radio Unit mounting hardware in the normal

fashion, connect the Dual Control Cable connector (P3) to the Radio Unit. Tighten the two jackscrews on P3. Next, connect the Accessory Cable (19B802554P1 or P2) Connector (P1) to the Dual Control Cable Connector (P2), and tighten the jackscrews on P2. Connect the power cable, and install Radio Unit in mounting bracket.

3.After installing the Auxiliary Control Unit in the normal fashion, connect the Dual Control Cable (P1) to Auxiliary Control Unit, and tighten jackscrews.

4.Connect the Remote Mount Accessory Cable (19B802554P6) to the Auxiliary Control Unit.

5.A yellow Ignition Sense lead is provided on the Dual Control Cable and the Front Mount Accessory Cable. If the “Ignition Sense” feature is enabled on the Radio Unit, it is necessary to connect only one of the yellow leads provided, whichever is convenient. Tape back the unused yellow lead (See Page 20 for details).

6.Install the Speakers in convenient locations near the Radio Unit and Auxiliary Control Unit.

7.Install a relay (19A149299P1) from the kits supplied at a location near the leads from each speaker. For mounting, use the #8 X 3/4” sheetmetal screw and nutplate supplied with each kit.

8.At a convenient point cut one of the wires in each of the 2-wire speaker cables, spread the leads, and strip the ends. Crimp a 1/4” tab receptacle to each end.

9.Radio Unit Speaker: Connect the lead nearest the speaker to Pin 87A of the relay. Connect the lead nearest the connector to Pin 30 of the relay. Connect the connector to the Accessory Cable P2 (Refer to Figure 33).

10.Auxiliary Control Unit Speaker: Connect the lead nearest the speaker to Pin 87 of the relay. Connect the lead nearest the
