Electric circuit device provided on components necessary for controlling engine of vehicle

摘要

The work for connecting a wiring harness in assembling an engine, especially, in assembling components in an engine compartment, is simplified by connecting a wiring harness for transmitting electric signals at the same time the components are assembled. A member of a connector connected to a first harness is mounted on a jointing and attaching surface of an air suction pipe and the other member of the connector connected to a second harness is mounted on a jointing and attaching surface of a throttle body so that the connector members are joined and connected to each other at the same time when the air suction pipe and throttle body are joined and secured to each other. Thereby, the harness necessary for transmitting signals is connected at the time of assembly of the parts.
