Safety Precautions

Observe the following for all installations, especially in the engine compartment due to lack of room:

• Route lines of all types (e.g. for fuel, hydraulic, EVAP canister system, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed.
• Watch for sufficient clearance to all moving or hot components.
• Fuel system is under pressure! Before opening system, place rags around the connection point. Then release pressure by carefully loosening connection.
• Test equipment must always be secured to the rear seat and operated by a second person.
• Test and measuring equipment that is operated from the passenger seat, the person seated could be injured in the event of an accident involving deployment of the passenger-side airbag.
• Do not touch or disconnect ignition wires when engine is running or turning at starting RPM.
• Only disconnect and reconnect wires for injection and ignition system, including test leads, if the ignition is turned off.

The use of nails, paper clips, or another unauthorized materials to back-probe electrical harness connectors is strictly prohibited and may cause damage to the electrical harness connectors, terminal ends or damage to a component. Use only the manufacturers test lead kit or an equivalent aftermarket test lead kit for back-probing all electrical harness connectors.
