instructions below to move it to the new PCP-Mk2.
1. Disconnect the red-and-black harness from the old user interface's two-pin "ride thru"
header.
2. Remove the three screws securing the RideThru Option Card to the old user interface.
• Set the three screws aside for reinstallation.
• Keep any spacers that were installed with these screws. You will need a total of three

(ETC part number HW9444) are included in the Power Control Processor Mk2

removed above, placing one spacer on each screw between the user interface and the
RideThru Option Card bracket.
4. Connect the free end of the red-and-black harness on the RideThru Option Card to the two-
pin "ride thru" header on the new user interface.
