PRECAUTIONS 37 PRECAUTIONS When reconnecting the wire harness or components, make sure that connectors and terminals are fully engaged. Electrical malfunction may occur otherwise. Test wiring connections by ‘wiggling’ the wires in the connector (inset). Repair or replace wiring as necessary. Dirty, corroded, loose, or damaged terminals/wiring insulation creates poor connectivity, short circuits, and other malfunctions. Clean or repair terminals/ wiring as necessary. Static electricity will damage the vehicle ECU (Engine Control Unit) and other sensitive components. Avoid touching the terminals and connectors of sensitive electrical components. When testing sensitive components and electrical circuits with an ohmmeter or voltmeter, make sure that the probes will not damage the electrical system. Do not expose the ECU or other sensitive electrical components to water, heat or shock of any type. Damage to the component will occur if exposed to any of these conditions. When disengaging electrical connectors, never pull on the wire. Always pull the connector apart by disengaging the locking tab and pulling on the connector body. Damage to the wiring or connector will occur otherwise.
