Video Transcript for Brophy Wiring - Tools for Wiring - F4CT Review

Speaker 1: Today we're going to take a look at the Brophy circuit tester for the four-way flat tailor connectors. Now this circuit tester will plug into your trailer's wiring harness to check the conductivity of all your circuits between your vehicle and your trailer so it'll quickly identify any lighting problems. And you can see it's very small and compact, so easy to carry with you.Does have the three LED lights you can see here and they do indicate which functions are working properly. So if I just zoom in you'll be able to see right above this first light here, it's says tail, middle one will say LT for left turn and the last one says RT for right turn. And at the very bottom under the last two, it'll say brakes.So we'll show you how this works. We're going to go ahead and plug this into some 12-volt power.

Scan back just a little bit. So we have a four-way that would be like on your trailer. So we'll go ahead and plug it in. And once we get that tester plugged in, you'll be able to see when I turn on the power, your first light comes on. So that means your taillights are working properly and your grounds working because you're getting the taillight working there.

And then if we hit the left turn, you can see with the left turn working, light is flashing. And then if we do the right turn. And I can see the right turn light is working. And then when you apply your brakes you'll be able to see both lights are working. So that's showing all the four functions are working on your four-way.Go ahead and turn off our power, unhook our tester.

But that should do it for the review on the Brophy circuit tester for the four-way flat trailer connectors.

great product and fast service, would buy from them again. 688682

Easy. Simple. Anybody with no electrical knowledge can use this! I would suggest using this to test the functions (as shown in the video) immediately after attaching the plug-in harness and before you put all the pieces of trim back in place. Gotta make sure it works beforehand! 661185

Great product to be able to test your electrical install before you close it all up and try to hook up a trailer and cross you figures it was done correctly. I was able to install my own wiring harness and use this tester to make sure everything was good. Well worth the extra few dollars. 672787

This product makes it very easy to check for correct wiring on flat four light plug. It is a small piece so I will probably put some kind of a key ring item on it so that it will be easy to find if I misplace it somewhere. 589928

I bought this at the same time I bought a Hopkins Plug-in Simple Wiring Harness With 4-pole Connector. It worked exactly as advertised and let me test the wiring harness installation in advance of hooking up a trailer. Both products are excellent, and the folks at etrailer exceeded my expectations in all areas, particularly the very fast response to my order. 628773

  • Sporadic Lighting Functions for Trailer Lights on a 2017 Ford Edge
  • For starters, the Curt T-Connector Vehicle Wiring Harness part # C56292 is for a 2017 Ford Edge with the Sport and Titanium package. If you have the SE and SEL package on your 2017 Ford Edge then you will want to use the Curt T-Connector Vehicle Wiring Harness part # C56272. With that being said an LED trailer connector tester like part # F4CT do not always work with all trailer wiring harnesses so this could be the issue.
