Long-reach positive-polarity harness designed for extended alternator installations

This 27-foot Positive P-Type harness is engineered for van, RV and long-chassis applications where greater routing distance is required between the alternator, regulator and battery connection points. Purpose-built for positive-field (P-type) alternator systems, it provides full-length control, sense, and signalling conductors in a durable, abrasion-protected assembly. With colour-coded wiring, sealed terminations and long-distance signal integrity, it ensures reliable alternator management across vehicle platforms that demand extended harness routing.

Key Features

• Optimised for long vehicle layouts: Extended 27-foot harness length supports routing through vans, RVs, buses and compartmented engine spaces without splicing or extensions.
• Positive-field alternator compatibility: Designed for P-type polarity systems to ensure correct field control output and stable regulated charging performance.
• Full signal pathway delivery: Provides field control, voltage sensing, switched ignition inputs and supporting control signals required for intelligent regulator operation.
• Colour-coded conductor scheme: Simplifies installation, wiring identification and terminal mapping throughout longer routing distances and concealed runs.
• Durable braided protective sleeving: Engineered to withstand vibration, chassis movement, abrasion and heat exposure common to engine-bay and underneath vehicle environments.
• Sealed multi-pin termination: Rugged interface connector ensures secure engagement and reliable electrical continuity in mobile and moisture-exposed systems.
• Extended system reach: Ideal for builds requiring regulator placement away from the engine bay or where battery and alternator locations are significantly separated.

Designed for longer-form vehicle layouts, this harness provides a complete alternator interface path with the correct polarity structure, durable protection and dependable signal integrity over extended distances.
