Questions & Answers

On a hayes 81789 quick connect dual mated universal/4 leads wiring harness, how do I connect the wiring? Is it possible to put this on a Ford 150?

Depending on the Ford's model year, you may be able to purchase a wiring harness that connects to the factory wiring. If not, ground is white, battery positive is black, trailer brakes are blue, and the brake light switch is red.

What do the loose wires that are visible on the Hayes 81789 quick connect connect to?

I don't recall the exact diagram because it's been a while, but there should be a wiring diagram with the color code on the controller, br>br>I believe one goes to 12 volt power, one to the brake light, one to the ground, and one to the trailer's electric brakes, follow the brake controller's manual for proper connections.

I'm curious about the wire gauge. Is it also capable of supporting four 18-watt Cree LEDs?

This was a Hayes brake controller connection whip. I'm not sure what you're hoping to accomplish with it based on your description. My original connector was able to fit in this way.

Excellent quality, exactly what is required for the installation of a Hayes custom brake controller
5/5

Summary: This high-quality part is exactly what you need for a Hayes custom brake controller installation. br>br> Most newer Hayes brake controllers have a connector that connects directly to a high-quality pigtail setup. If your controller came without a connecting cable and you can't use one of the "Big 3" connector cables for a Ford, GM, or Chrysler plug-in vehicle, you'll need this item. with regard to If your vehicle has the appropriate socket, you should use one of those cables, which simply plug in on both ends. br>br>This item works in vehicles that lack a socket and require you to wire it in yourself. The controller plugs in, and the other end is connected to the vehicle trailer wiring as required.

Harness for the brakes
5/5

I ordered this to work with a new brake controller that I had purchased. The picture showed the controller without the plug and only wire, but it came with the plug, and I didn't want to cut the plug off, so I ordered this, which I believe made the hook up easier because it gave me a little more wire to work with and figured if I wanted to move the controller unit to a different truck,br>since this was an older 1970's truck the "universal" harness suited the situation.
