Matching OEM part numbers 12124580 (terminal) and 12089307 (sheath), these terminals restore factory-quality electrical contact at GM connector housings — eliminating intermittent faults, voltage drop, and signal errors caused by corroded, damaged, or missing terminals.

OEM Part Numbers

• 12124580 (female crimp terminal)
• 12089307 (terminal sheath / seal)

Key Specifications

• Terminal Type: Female crimp terminal
• Application: General Motors automotive connector housing repair
• Accessory: Protective sheath / wire seal (OEM 12089307)
• Fit Type: Direct OEM replacement
• Compatible Housings: GM connector housings accepting OEM 12124580 terminal specification

Why Replace Crimp Terminals?

Corroded, bent, or missing crimp terminals are a leading cause of intermittent electrical faults in GM vehicles. Symptoms include:

• Intermittent sensor faults and fault codes
• Voltage drop at connector causing incorrect sensor readings
• Intermittent no-start or stalling conditions
• Communication errors between ECU and control modules

Replacing the terminal with an OEM 12124580 specification unit and sealing with the OEM 12089307 sheath restores factory contact resistance and weatherproofing without replacing the entire connector or harness.

Features & Benefits

• OEM-matched terminal geometry: Precise crimp terminal dimensions match GM connector housing cavities for OEM 12124580
• Factory contact quality: Restores low-resistance electrical contact at the connector interface
• Protective sheath included: OEM 12089307 sheath seals the wire entry point against moisture and debris
• Crimp installation: Standard automotive crimp tool installation — no soldering required
• Direct replacement: Fits existing GM connector housings without modification

Installation Guide

1. Use a terminal removal tool to extract the damaged terminal from the connector housing cavity.
2. Cut the wire at the damaged terminal, leaving sufficient length for re-termination.
3. Slide the OEM 12089307 sheath onto the wire before crimping.
4. Strip the wire to the correct length and crimp the OEM 12124580 terminal using an appropriate automotive crimp tool.
5. Slide the sheath over the terminal wire barrel and seat it in position.
6. Insert the new terminal into the connector housing cavity until it locks in place.

Frequently Asked Questions

Q: Which GM vehicles use OEM 12124580 terminals?
A: OEM 12124580 is a widely used GM terminal specification across multiple GM brands (Chevrolet, GMC, Buick, Cadillac, Pontiac, Saturn). Cross-reference against your vehicle’s wiring diagram or parts catalog to confirm compatibility.

Q: What wire gauge does this terminal accept?
A: Refer to the OEM 12124580 specification for compatible wire gauge range. Standard GM terminal specifications typically cover 18–22AWG wire.

Q: Do I need a special crimp tool?
A: A standard automotive terminal crimp tool is required. Do not use pliers — improper crimping will result in high contact resistance and intermittent faults.
