Hey Jose, I attached a diagram for the wiring harness of the Replacement Digital Relay Box # PXXACRG12RB that shows that the gray wire runs to the upper unit. The heat strip part # ACMHD doesn't have wiring that you would have to run as it basically just plugs right into the upper unit with a plug and play connector.

Hey Jose, how did things go with adding the heat strip to your Advent AC? Did the plug-and-play connection work smoothly with the upper unit? Your update could make it easier for others trying the same setup.
