2-Pin 1-968642-1 / 1-968643-1 Sealed Fog Light & Horn Connector – Automotive Wiring

Direct-fit replacement for TE Connectivity / AMP part numbers 1-968642-1 (female socket) and 1-968643-1 (male plug), a 2-pin sealed connector pair used for automotive fog light assemblies and horn circuits. This connector series is designed for exposed underbody and front fascia locations where water spray and road debris are constant factors.

• Terminal Material: Copper alloy, tin-plated
• Voltage Rating: 12V DC
• Current Rating: Up to 15A per pin
• Operating Temperature: -40°C to +105°C

Applications

• Front fog light assembly: Power and ground connection to fog lamp housing
• Horn circuit: Relay output to horn unit (single or dual horn)
• Daytime running light (DRL) module: 2-pin power connector
• Auxiliary lighting: Driving lights, light bars, and off-road lighting harnesses
• Underbody sensors: Parking sensors and proximity sensor wiring

Fog Light Connector Failure – Diagnosis

Fog light connector failure is common on vehicles driven in wet or salty conditions. Symptoms and diagnosis:

• Fog light inoperative: Check fuse first, then measure voltage at connector Pin 1 with fog lights switched on – should read 12V. No voltage indicates a wiring or relay fault upstream.
• Fog light flickers: Wiggle the connector while the light is on – flickering during wiggle confirms a loose or corroded terminal.
• Both fog lights dead simultaneously: Check the fog light relay and fuse before replacing connectors – a single connector failure typically affects only one light.

Horn Connector Failure – Diagnosis

• Horn not working: Measure voltage at 1-968643-1 Pin 1 while pressing horn – should read 12V. No voltage indicates relay or switch fault. 12V present but horn silent indicates a failed horn unit.
• Horn sounds continuously: Short circuit in horn relay circuit – inspect connector for water ingress causing pin-to-pin short.

Frequently Asked Questions

Q: What is the difference between 1-968642-1 and 1-968643-1?
A: 1-968642-1 is the female socket housing (connects to the fog light or horn unit); 1-968643-1 is the male plug housing (on the vehicle harness side). For a complete repair, you typically need the female socket (1-968642-1) which connects to the lamp or horn body.

Q: Can this connector be used for aftermarket fog lights?
A: Yes, provided the aftermarket fog light uses a 2-pin connector with the same terminal pitch. Many aftermarket fog light kits include a pigtail harness – splice the 1-968642-1 connector into the existing harness for a plug-and-play installation.

Q: What wire gauge should I use for a fog light circuit?
A: Standard fog lights draw 35–55W (3–4.5A at 12V). Use 18 AWG (0.5 mm²) minimum. For LED fog lights with higher-wattage drivers, use 16 AWG (1.0 mm²) to prevent voltage drop.
