This Installation and Wiring Guide will guide you through the installation of your

STINGER 4 ECU to your vehicle.

Warning:

Always disconnect the battery cables when doing electrical work on your

vehicle. The STINGER 4 ECU must be completely disconnected from the

electrical system before doing any form of electrical welding on the vehicle.

Note:

Installing an engine management system is a complex exercise and should be done

only after careful planning. Damage may be caused to engine components if care is

not taken during the installation and set-up of any engine management system. If you

are unsure about how to wire any components of your engine, please consult an

experienced installer for advice.
