Windshield Wiper Switch Wiring Connector | 69-79 Bronco, 68-79 Ford Truck SKU: 6329

Windshield Wiper Switch Wiring Connector | 69–79 Bronco, 68–79 Ford Truck

Restore proper wiper function on your classic Ford with this OEM-style windshield wiper switch wiring connector, built to plug directly into the back of the factory wiper switch. This connector accepts factory-style blade terminals, allowing you to rebuild or repair the original harness without cutting, splicing, or using butt connectors. It’s the clean, correct solution for fixing damaged or brittle wiper switch plugs while keeping the wiring true to Ford’s original design.

Pro Tip: When reinstalling the connector, verify each wire is indexed to the correct blade terminal position—misalignment can result in intermittent wiper speeds or switch overheating.

• OEM-Correct Connector Body - Matches the original plug used on 1969–79 Broncos and 1968–79 Ford trucks.

• Accepts Flat Blade Terminals (Not Bullet) - Designed for proper Ford-style open-barrel blade terminals—no splicing or aftermarket terminals needed.

• Restores Reliable Wiper Operation - Ensures solid electrical contact between the dash switch and the wiper system.

• Factory-Style Harness Repair - Rebuilds the connection cleanly without modifying the original wiring layout.

• Durable Molded Construction - High-quality connector body with proper terminal retention for long-term reliability.

• Terminal Type: Accepts OEM-style flat blade terminals (not included)

• Installation: Crimp new terminals to your existing wires and insert into connector—no cutting or splicing required

This OE-type wiper switch connector restores factory-correct wiring using stock style terminals—no splicing required—for classic Broncos and early Ford trucks.

Continuity test data for 1969-77 Ford Bronco & 1968-72 Ford F-Series Truck

Use this wiring schematic to verify continuity and troubleshoot your Classic Ford Truck or Early Bronco windshield wiper switch wiring. This chart is intended for testing the factory wiper switch with the connector unplugged and a multimeter set to continuity or ohms, allowing you to confirm proper switch function before chasing wiring issues or replacing parts. It’s especially useful on original or aged harnesses where wire colors may have faded or been repaired over the years, helping you determine whether the issue is in the switch itself or elsewhere in the wiper or washer circuit.

Switch Positions and Continuity Between Terminals

With the switch unplugged, use a multimeter in continuity mode and confirm terminal-to-terminal continuity matches the chart below. This is the quickest way to confirm switch function before you start replacing parts.

Switch Position	Continuity Between Terminals
Off (Park)	763 – 63; 58 - 615
Low	763 - 63 - 58
High	763 – 63 – 56
Washer On	941 – 950

Wiper Switch Wire Colors and Terminal IDs

Match each terminal ID to its wire color before testing. If your harness has been repaired over the years, confirm by function (power-in, park power, low/high outputs) instead of color alone.

Terminal ID	Wire Color	Circuit Function
763	Orange/White	Power In
63	Red	Park Power
58	White	Low Speed
56	Blue	High Speed
615	Black	Park Circuit Power
941	Black/Green	Washer Squirter
950	Black	Wiper Power In

Quick Notes for Clean Diagnostics

• Test at the switch first: If the switch continuity is correct, move downstream to the motor/washer circuits.
• Confirm grounds: Weak/dirty grounds can mimic bad switches in both Early Bronco and classic Ford Truck wiring.
• Park issues: If the wipers won’t park, focus on the Park Power (63) and Park Circuit Power (615) paths.
