New Truck/Trailer Electronic Technology for Safer, Easier Juice

EZ - Connector
If you're new to towing you may fully understand the EZ Connector, a wonderful tool. If you are a trailer expert and spent time with that little screw driver redoing your trailer plugs after they pulled apart or using your knife to scrape corrosion off the trailer plug blades and off course using the straight edge screw driver to bend the blades so they will connect to the male plug, you'll relate to a better way. Trailer brakes in general need monitoring and maintenance more than any other part of your trailer for safety reasons. EZ-Connector will make the wire connection issue one thing less to worry about (when brake lights and blinkers aren't working and you don't know it.) Those of use that tow trailers every week know how many times we drop the coupler on the ball and plug in the wire connection (and wiggle the connection for contact.) This is an ideal electrical connection for snow plows and farm machinery. I remember my big round balers and the guidance electrical system wiring exposed to all the dust and corn planters have sophisticated monitors that all could use a weatherproof electronic connection.

EZ is a magnetic connection, powerful magnets. Just get the male end near the female plug and "pop" it sucks together. A tab slot align the socket and plug to match the right connections. The male end has two silicone o-rings, the cables have sealant injected inside, all to make the system water proof. If you can keep the water out, you can keep the mud and all the corrosive chemicals used to dissolve ice on the highway out.
Because the EZ Connector is magnetic, it's a no brainer to understand that the system will breakaway if your trailer cable gets tangled. Right top picture shows the dummy plugs to keep dirt and water out of the EZ-Connector when you aren't using them. This is quality all the way. When you first look at EZ you'll be impressed that it's made to last with trouble-free function.
According to Joe Cardoza (the big cheese at EZ) inside the truck socket, the cable is crimped three times. It is also reinforced with a stainless steel hog-ring on the inside to take any strain.  Every unit is 100% tested, not a sample testing as is common in the electronic industry.
I tow dozens of new trailers each year for reviews and have adaptors for 7 blade to 6 pin and 7 RV blade to 4 pin  When EZ-Connector brings out the plug adaptors this spring, I'll go back and do the butt connectors and heat shrink wrap and cut off the old RV 7 blade plug. Semi truck connections will be out latter also.
With the T-connector I use, it only took 15 minutes to install on my truck. EZ-Connector also has a hard-wired version if you don't have a factory tow package on your truck or SUV. They sent me the kit for GM/Ford. I cut out the V in the wiring harness connector with a hacksaw blade and needle nose pliers. Hopefully in future they will get Delphi to make a plug just for Ford connection.
Bottom line, yes it's expensive, but you buy more expensive aluminum trailers for a reason. Quality is never cheap, being a farmer for decades means I'm naturally frugal. But I'd have no problem shelling out $100 for this trailer wiring system. Piece of mind and safety have value.

Pro Plug
I've had trailers along time. Spent my share of nights with a flashlight in my mouth in the rain as I work on trailer lights. Fuel injection and electronics make our trucks more trouble free, now trailer wiring and electronics make tracing trailer wire problems a breeze. Pro Plug is a 7 pin female plug with a twist. It has a circuit board that makes wiring easy with self-test lights and wire terminals which are much easier than taking a plug apart and running wires in a hole. You can mount the Pro Plug flat or on a bracket. It uses 3M VHB (Very High Bond) tape for quick placement that is rated to hold 1500 lbs. 3M tape is used in many horse and cargo trailers to hold the sheet metal to the frame. Using 3M tape makes installing RV Pro Plug inside your truck bed simple. There are 3 rubber plugs on the side of the Pro Plug  and two on the back, so finding a good place to run your wires into Pro Plug is convenient.
Now you can test your tow vehicles trailer wires with the LED lighted barrier strip and connect other wires to a power source such as snow plow, slide in camper or for 12 volt power in the bed. When connected, the LEDs in Pro Plug will light up when electrical power is at the Pro Plug terminals. Actually I think I'll get another Pro Plug and use it to build a circuit board for my trailer so I can add accessories to the trailer in an organized manner. It would also make wiring in a second trailer easy like a boat behind a 5th wheel. Made in the USA. Patent Pending.
