Almost every circuit on this harness is pre-terminated at both ends. All wires are color coded and labeled and all wire leads are pre-cut to proper lengths. Our harness uses an OEM style bulkhead connector that attaches to the bulkhead without any special brackets or modifications. The blade type fuse block wiring is factory installed and machine crimped. The most Painless way to wire your 75-86 CJ Series Jeep.
