2. Install the Power/Comms Harness. Route the red and black wires to a 12 volt battery.
DO NOT CONNECT TO BATTERY, UNTIL INSTALLATION IS COMPLETE.
Use the cable ties provided to secure the Power/Comms Harness away from hot and
moving parts and to avoid chaffing and wear.
3. Plug the ‘Switched Power’ connector that is located on the Power/Comms Harness, into
the ‘Switched Power’ connector on the ZYNX Power Cable. If this connection is already
utilized, connect it via the A1953 Power Splitter Harness. This connection ensures that
the Spray ECU is only powered up when the ZYNX Console is switched ON.
4. One end of the Power/Comms Harness has 'DB 9-Pin' Comms Cable connection.
Connect this cable to the next available COM Port at the back of the ZYNX Console.
5. Connect the other end of the Power/Comms Harness to the 16-pin connector marked
‘POWER/COMMS’ on the Spray ECU.
