Painless 28 Circuit Wiring Harness Without Switches



Painless 28-Circuit Direct Fit 1966-77 Bronco Harness without switches
The result of nearly two years of painstaking engineering, this harness is the most comprehensive, best designed system available anywhere. Designed with input from Bronco owners everywhere, this harness sets a new standard. Not just an update of the existing Bronco harness, this is a completely new harness from top to bottom. It includes a molded plastic glove box to replace the factory cardboard one. The new glove box contains a cutout which allows the 20- circuit covered weatherproof fuse block to be installed in the factory location. An additional 8-circuit covered weatherproof auxiliary fuse block is located under the dash near the 20-circuit fuse block location.

Other features include factory-style molded exterior light connectors, Ford turn signal connectors, Ford dimmer switch connector, and 80+ page instruction manual. This new harness follows the factory routing so installation is a breeze on any 1966-1977 Bronco.

Like all Painless harnesses, these come with the highest quality XL wire, factory machine crimps and the terminals and connectors you'll need for a successful installation. The straightforward design, printed wire and detailed instructions make that installation a breeze.

Please consider upgrading the headlight harness. The Bronco light switch can barely handle the current needed to run stock headlights. Many have had the flickering Bronco headlight syndrome. The stock headlight switch definitely can't handle the current needed to run modern H4 bulbs. The way the Bronco is wired, the power runs from the battery into the dash, branches off a few times, then into the headlight switch. The headlights are then drawing power from this switch. What that means is after all the voltage drops, you end up with lower voltage at the headlights. The Night Lighter harness uses a relay system to put direct battery voltage (often 14.4 volts) directly to your headlights creating a brighter light.

Plug the harness in and the old light switch activates the new harness and the load bearing relays to bring power from the battery directly to the headlights. WH recommends adding the Night Lighter to any stock or after market wiring harness.

* Please make selection

* Please consider the WH wire loom kit. It includes more then enough loom for the complete Bronco harness.
