Ecu Installation - Merlin POWERGUARD PRO User's Installation Manual

Mount Components:
Mount the components in the agreed locations with the specifying Engineer. We
recommend installing directly to bulkheads using stainless steel bolts. All nuts should
be either of the Nyloc type or protected with a shake proof washer. Appropriately
sized washers should be used to mount components to distribute component weight
and loadings.
Plan and lay in cables:
Lay in the cables / wiring to the various components as per the system diagram
supplied by the specifying / design Engineer. Ensure all cables are routed away from
vehicle control devices and are suitably fixed and secured. Cables and wiring should
not be installed above vehicle access points.

ECU INSTALLATION

The PowerGuard Pro ECU is supplied with 2 Mounting Flanges. Each flange has a mounting slot
to enable fitment of M5 bolts. Ensure that the unit is securely mounted to the vehicle using
suitable bolts, washers and nuts. Unit dimensions are as detailed below:
