Installing the RS232 ECU To Display Loom
The RS232 ECU To Display Loom connects the C125 loom to an ECU via its
RS232 communications connector.
NOTE:
The RS232 communications connector is the socket that you would
normally use to connect to your ECU for tuning.
Installation method – if C125 came pre-configured
1. Plug in the C125, buttons and GPS.
2. Connect the C125 to RS232 ECU adapter loom to the ECU plug on your
C125 loom. Plug the other end into your ECU communications connector.
An additional cable/adapter may be required in conjunction with the RS232
adapter for some ECU’s.
3. Plug the cigarette lighter power adapter into a spare power supply socket. If
your vehicle does not have a power supply socket, cut off the adapter and
connect the red wire to a fused 12 V source and the black wire to chassis
ground.
4. Power up the car, including turning on the ECU. The number in the top right
of the display should change to show the current Engine Temperature.
NOTE:
If the Engine Temperature is not displayed, then either your ECU or
C125 isn't correctly configured. Follow the not pre-configured instructions.
