6.2.5.7 Disconnect and Discard the CT-PET Positions Cable (P/N 2318721)
The ETC I/F J8 connection consists of three cables and a pigtail. Two cables go to the PET and CT

Board. Follow the instructions in this section to remove the pigtail and the PET and CT limit switch
cables.
Note: For best results, tilt the ETC mounting tray to access the connectors. Use a flat-blade screwdriver
to unfasten the slotted (captive) screw located bottom center.
