This harness allows the end user to run and terminate their own harness for the MoTeC M150 ECU.

This product is what most MoTeC wiring professionals start with when constructing a custom harness, ensuring quality and reducing the labor to prepare an ECU for operation.


This is a very high quality, un-termed wiring harness utilizing Mil Spec 18awg Tefzel wire.  The wires are color coded and come with a pin-out list detailing the color and function of each wire.  The harness comes with the ethernet connector already terminated and attached.
