Automotive Crimp Terminal – OEM 1674742-1 / 1123343-1 | 50pcs Male & Female

The OEM 1674742-1 / 1123343-1 are precision automotive crimp terminals (sheath contacts) used in wire harness repair and connector assembly. Sold in 50-piece packs for Male and Female variants, these terminals are compatible with automotive connector housings using the 1674742-1 / 1123343-1 contact series.

Key Specifications

Why Crimp Terminals Fail

Automotive crimp terminals corrode from moisture ingress, vibration-induced fretting, and thermal cycling. Corroded or pushed-back terminals cause intermittent circuit faults, high resistance connections, and voltage drop issues that trigger sensor fault codes without obvious wiring damage. Replacing terminals restores clean contact resistance and eliminates ghost faults.

Variant Guide

• 50pcs Female – 50x OEM 1674742-1 female crimp contacts (socket side)
• 50pcs Male – 50x OEM 1123343-1 male crimp contacts (plug side)

Installation Notes

• Strip wire insulation to 3–4mm before crimping
• Use a ratchet crimp tool rated for the appropriate wire gauge
• Insert terminal into connector housing until the locking tab clicks
• Pull-test each terminal after insertion to verify retention
• Apply dielectric grease in moisture-exposed locations

Frequently Asked Questions
