The Painless Wiring CJ2-5 Jeep Wiring Harness with Thru Firewall Grommet is a 22-circuit complete electrical solution designed specifically for classic Jeep CJ models from 1945 to 1975. This pre-assembled harness eliminates the confusion and labor of sourcing individual components and routing wires through a complex firewall installation, providing a factory-quality backbone for restorations, custom builds, and modernization projects where original wiring has deteriorated or been removed.
The 22-circuit design accommodates all essential electrical loads on classic CJ platforms—engine controls, ignition, lighting, charging, and auxiliary circuits—without requiring custom modifications or splice work. The integrated thru-firewall grommet seals the passage of wires from engine bay to interior, reducing moisture intrusion and protecting conductors from abrasion against sharp firewall edges. This attention to detail is critical in restoration work, where water and corrosion are the primary enemies of reliability in older vehicles.
The complete kit approach means you receive all connectors, terminals, and integration points pre-fabricated to OEM specifications, dramatically reducing installation time compared to building a harness from individual components. This harness is ideal for restorers, off-road enthusiasts, and classic Jeep collectors who need a dependable, proven electrical foundation. Whether you're performing a frame-off restoration or converting from 6-volt to 12-volt systems, this wiring harness is designed to meet your needs.
