Installing the C125 Input Loom
The C125 Input loom is a fast way to add sensors to your C125 when you
have added the I/O upgrade. Following these instructions, you can quickly
add wiring for 6 AVs, 2 ATs, 2 Digital and 3 Speed inputs to your vehicle’s
loom.
Installation Process
1. Connect DTM 4 pin male of the Input loom to GPS DTM 4 pin female
connector of the main loom.
2. Connect DTM 4 pin female connector of the Input loom to the GPS
connector. The purpose of this connection is to supply 5 V and 0 V to the
sensors
.
3. Remove the main 34 pin C125 connector from the back of the C125.
4. Unlock the C125 connector by pushing in the long white locking tab.
5. Remove white plugs from pins 3, 4, 5, 6, 12, 13, 16, 17.
6. Insert pinned wires into the C125 connector as follows:
• AV1 – blue wire into pin location 3
• AV2 – green wire into pin location 4
• AV3 – purple wire into pin location 5
• AV4 – grey wire into pin location 6
• AV5 – yellow wire into pin location 12
• AV6 – white wire into pin location 13
• AT1 – brown wire into pin location 16
• AT2 – orange wire into pin location 17
7. Secure the pins in place by pushing in the two locking tabs on the C125
connector. If the two locking tabs are difficult to push back, this indicates
that one of the inserted pins is not seated correctly.
8. Run the AV and AT wires to the locations required for your new sensors.
Notes:
• The red wires are 5 V
• The black wires are 0 V
• Coloured wires are the AV and AT wires
• You can shorten the looms as required by cutting them shorter
• You should loop and tie up unused looms for future use
