46-Pin Automotive Waterproof Connector – 13647470, Heavy-Duty Plastic Wire Harness Connector

Part number 13647470 is a 46-pin heavy-duty waterproof automotive connector used in truck, agricultural, and industrial vehicle wiring harnesses. High pin count connectors in this range are used for main harness connections between major vehicle systems — cab-to-chassis, ECM-to-harness, and implement-to-tractor interfaces — where consolidating many circuits into a single sealed connector reduces harness complexity and connection points. The waterproof construction (IP67) ensures reliable operation in the harsh environments of commercial and agricultural vehicles.

Key Specifications

• Part Number: 13647470

46-Pin Connector — Application Context

46-pin connectors are used where a large number of circuits must pass through a single sealed interface point. Common applications:

• Truck cab-to-chassis: Main harness connector carrying lighting, brake, suspension, and body circuits between the cab and chassis
• ECM harness: Engine Control Module main connector on diesel engines with complex sensor and actuator circuits
• Agricultural implements: ISOBUS and proprietary implement harness connections requiring 30+ circuits
• Body control: Body Control Module (BCM) main connector on trucks and buses

Frequently Asked Questions

How do I identify the correct replacement for part number 13647470?

Cross-reference 13647470 with the vehicle’s parts catalog or wiring diagram. This part number may be an OEM number from a specific vehicle manufacturer (Volvo, Scania, DAF, or similar European truck brands use 8-digit part numbers in this format). Verify the pin count (46), connector gender (male or female), and mounting configuration against the original connector before ordering. If the part number is not visible on the connector, measure the connector dimensions and pin count for cross-referencing.

What contacts are used in 46-pin heavy-duty connectors?

Contact size depends on the specific connector series. Common options for 46-pin heavy-duty connectors: Deutsch HDP20 size 20 contacts (7.5A, 20–24AWG) for signal circuits; Deutsch DT size 16 contacts (13A, 16–22AWG) for power circuits. Verify the contact size against the connector’s datasheet before ordering replacement contacts — mixing contact sizes within a connector is not permitted.

Can I repair individual terminals without replacing the entire connector?

Yes. Individual terminal replacement is the preferred repair method for high pin count connectors — replacing all 46 terminals is significantly more labor-intensive than replacing 1–3 damaged terminals. Use the appropriate extraction tool for the contact size, remove the damaged terminal, crimp a new terminal onto the wire, and reinsert into the housing.

Typical Applications

• Commercial trucks: Cab-to-chassis and ECM main harness connections
• Agricultural equipment: High pin count implement and tractor harness connections
• Construction equipment: Multi-circuit control harness connections on heavy machinery
• Bus & coach: Body control and lighting harness connections
