Jeep CJ Factory Style Wiring Harness

Painless 10150 wiring harness.

1976-1986 Jeep CJ factory style replacement wiring harness.

Almost every circuit on this harness is pre-terminated at both ends on this three section harness.

All wires are color coded and labeled and all wire leads are pre-cut to proper lengths.

This harness uses an OEM style bulkhead connector that attaches to the bulkhead without any special brackets or modfications.

The blade type fuse block wiring is factory terminated and machine crimped.

Included is a fully integrated ground circuit that connects directly to the negative side of the battery and provides a clean ground source to every component, as well as offering individual wires to help ground the dash and core support. This is a key addition for those using fiberglass bodies.

Connections for more factory CJ options have also been added. These additions include:

Factory V6 & V8 Tachometers- Inline connections are now provided at the ignition switch, just like a factory harness, that plug into the wire leads found on factory V6 & V8 tachometers.

Factory Clock- Two connectors that provide power and ground to the clock and clock backlighting that plug directly into a factory clock. These connectors can be removed to allow connection to a universal CJ clock as well.

Automatic Transmission Steering Column- Reverse switch and neutral safety switch connections for those using automatic transmission columns.

Under Hood Light- A factory style connection is now supplied in the engine harness. This connection will simply plug directly into the factory under hood light.

Manual Transmission Pigtail- Comes with a transmission pigtail. This pigtail allows for the total replacement of the neutral safety switch, reverse switch, and four wheel drive indicator switch wires. Some assembly will be required to this pigtail based on the transmission your CJ currently has, instructions and details are provided.

Factory Tail Light Connectors- Factory style molded connectors for the tail lights are now pre-installed onto the tail harness, allowing for a true plug and play connection to those using factory tail lights. For those using aftermarket lights which do not have the factory molded connector, a pair of Weather –Pac connectors is also provided to produce a clean, weatherproof connection.

Molded Trailer Connector- Now included pre-spliced in the Tail Section of the harness is a connector for connecting to trailer lighting. This connector will supply tail light power, left and right turn/brake power, as well as a clean ground source. A mate to the pre-installed connector is even provided.

Factory Style parts Kit- This kit will provide factory style connectors and terminals for many visible connections. This makes for a cleaner appearing install. Also included are harness attachment clips that fit the ¼” holes left behind by the factory harness attachment clips.

Bulbs- Now includes all the bulbs needed for front turn/park and marker lights, rear turn/brake/tail and marker lights, as well as gauge cluster bulbs. Dielectric grease is also provided to prevent corrosion to the bulbs and headlight connections.

TECH NOTE: Harness is NOT equipped for computer controls nor is it engine specific. Water temp sender, oil gauge sender, alternator, starter solenoid, tach lead, ignition and fuel tank sender are NOT pre-terminated.
