What Are Heavy Duty Wiring Harnesses

The common adapter rule is that adapters should only be used to go from bigger to smaller plugs, but there is a wiring harness that can get around that rule. Manufacturers took a 7-Blade Plug and wired a 4 prong onto it so that we could plug into a 4 prong on the back of the tow vehicle. In addition to wiring on the 4 prong, they also wired on 3 extra wires. | |
Now all 7 wires on a 7-Blade plug can be hooked up to power from the vehicle.Harnesses are useful in upgrading vehicles which already have a 4 prong or 6 pin wired in, but need to use a 7-Blade plug. The harness takes advantage of the wiring work that's already been done, only requiring that the installer splice the extra wires needed. Above is an image of a harness that is commonly used when installing a brake control. There are several versions of the basic harness shown above. New innovations incorporate more and more options into these harnesses. |
Below is a brief look at the other styles of harnesses common in the industry.
