System Components Overview
The EZ-TCU™ system is made up of several main components. A TCU (Transmission Control Unit),
a wiring harness, a handheld user interface, and an RPM module. Please read through all of the
installation notes before beginning the installation.
TCU
TCU Installation Notes:
•
The TCU is water tight when connected to the wiring harness. It can be mounted in the engine
compartment or in the vehicle’s interior. It is good practice to mount the TCU with the
connector facing down. This way, there is less chance of moisture getting into the TCU if it
needs to be disconnected in wet conditions.
•
The TCU should not be mounted close to other electrically “noisy” components. In particular,
keep good spacing (try for 2 feet minimum) from ignition components (ignition boxes, coils,
distributors, etc.)
•
If mounting in the engine compartment, selecting a location towards the rear will make it easier
to route the communications cable to the interior to allow the handheld to be monitored while
driving. Optional, longer communications cables are available if needed.
•
There is an LED on the front face of the TCU – the side with the logo. It will flash if the on-
board diagnostics detects a problem (the LED is lit solid when the TCU is powered up and
working normally). To take advantage of this feature, the TCU will need to be mounted so that
the front face of the TCU is visible. The handheld will also indicate if any faults have been
detected.
