MoTeC Appendices 33
Appendix D – Wiring Details
To connect a single LTC unit, the Power/CAN Connector pins should be wired
according to the following table, taking into account general CAN bus wiring
requirements:
LTC/LTC-N Pin Battery - CAN Lo CAN Hi Battery +
1 2 3 4
SDL & SDL3
(CAN 0)
Ground
35 36
Power 12 V (see tip)
SDL3 (CAN 1) 29 30
ADL2 73,75 74,76
ADL3 (CAN 0) 73 74
ADL3 (CAN 1) 75 76
ACL (CAN 0) 5 6
ACL (CAN 1) 7 8
M84 B24 B23
M400/M600/M800 B24 B23
M880 47 48
Tip: To wire the LTC to power, connect either to the ignition switch for fast
sensor start up or connect to the fuel pump relay to prevent accidental battery
drainage
For wiring a CAN bus with several LTCs and any number of other CAN
devices refer to the example below.
PC Connection
The LTC connects to the USB port on the PC via a MoTeC UTC (USB to
CAN). The UTC is plugged into a CAN connector wired into the CAN bus.
Wiring Loom Connection
Care must be taken for power and ground wiring for the LTC. Each sensor
can draw over 3 Amps when cold if multiple channels of Lambda are used this
current draw will increase dramatically. Wiring size should be suitable for the
number of LTCs used.
