Engine Connections

It is good practice to ventilate the engine compartment prior to servicing any engine
components to remove any fuel vapors which may cause difficulty breathing or be
an irritant.
IMPORTANT: When routing all wire harnesses and hoses, ensure they are routed and
secured to avoid coming in contact with hot spots on engine and avoid contact with
moving parts.
1. Connect instrument extension harness ends to engine harness ends. Connector collar
must be fully engaged and secure. Tighten threaded connector collar of extension
