Prepare RFQ details before quotation

Connector set information

A harness connector RFQ should clarify whether the buyer needs plug, receptacle, terminal, seal, cavity plug, secondary lock or full connector kit.

Wire and terminal details

Wire size, insulation diameter, terminal series and crimp requirement are essential for correct housing and terminal matching.

Application and environment

The supplier should know whether the connector is used in body harness, engine harness, lighting, sensor, door system or outdoor location.

Sample and volume

RFQs should include sample quantity, target annual volume, drawing or reference model and project timeline.

FAQ

Common questions

Common procurement and engineering questions related to this topic.

Should terminals be included in a harness connector RFQ?

Yes. Housing and terminal should be reviewed together because crimp quality and terminal retention affect reliability.

What if I only have a connector photo?

A photo can start the review, but pin count, wire size, application and mating part information are also needed.
