3. Mount the communication module board
in the DEC 3+ controller.
Note: Requires DEC 3+ controller logic (red) circuit
board GM28725.
Note: Perform step 3 with GM91356-S4, -S5, or -S6
and GM32644-KP1 kit.
3.1 Remove the existing three nuts attaching the
indicator panel circuit board. Leave the existing
washers in place. The nuts will be reused.
3.2 Attach the three spacers to the indicator panel
circuit board studs. See Figure 10.
3.3 Position communication module board
GM49791-1 on the spacers.
Note: If procedure requires installing a communication
module board, refer to TT-1285 Program Loader
Software instructions for downloading firmware
version 1.23 or higher with red controller
board or 2.03 or higher with blue controller
board. The download should be performed in
step 8. Configure the DEC 3+ controller for the
remote serial annunciator.
3.4 Install three lock washers (X-22-7) from the kit or
from step 2.3 and the existing three nuts on the
spacers to secure the communication module
board. Do not overtighten the nuts.
4. Wire the communication module board
in the DEC 3+ controller.
4.1 Attach the 24-position ribbon cable GM32632
inline connector to the communication module
board P9 connector. The connector is polarized
and mates in one position only.
4.2 Attach the 10-position ribbon cable GM21340 to
the communication module board P8 connector
and the main circuit board P7 connector. The
connectors are polarized and mate in one
position only.

4.3 If the unit previously had the GM49791-2 gauge
drive circuit board installed, reconnect cable P10
to the communication module board.
4.4 High Battery Voltage. Locate T27 lead on the
indicator panel assembly and connect
communication board HBV harness GM35318.
Use the terminal connector on GM35318 with the
two leads together. Verify that the stripped end of
the harness is securely connected to
communication module board terminal TB5-12.
See Figure 9 for an illustration of the wiring
connection. See Figure 11 and Figure 12 for the
communication module board terminal strip
location and terminal designations.
