6. Connect the HVAC interface
harness into the HVAC interface, and then to the
wiring harnesses in the vehicle. These harnesses are the ones removed in step 11
of dash disassembly.
a. Then connect the 10-pin harness into the engine start/stop circuit board assembly.
Attention! There are (2) 10-pin connectors, one in the engine start/stop circuit board
assembly, and one in the touchscreen display. Use only the appropriate connector and
disregard the other one. If the incorrect port is accidentally used, the vehicle will need to be
reset by removing the battery for a couple minutes.
Note: Disregard the 4-pin flat to 4-pin stacked harness, it will not be used in this application.
7. Connect the 6-pin harness from the 5840 harness to the HVAC interface.
