A 4-Way trailer connector has the basic lighting functions only; running lights, left turn signal and brake lights, right turn signal and brake lights, and ground. A 7-Way has these functions and a 12 volt circuit, a circuit for electric trailer…
It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…
That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…
Hey Mark, thanks for reaching out, and good question. That “16/18 gauge” wording throws a lot of people off. The TowSmart 16 to 18 Gauge, 4 Conductor Wire #TS57QR isn’t all one size. It’s a 4-conductor cable with mixed gauges inside, two wires are 16…
The only difference between 7-Way Utility and 7-Way RV is the color of the wires. The pin outs are the exact same so either would work just fine with the other. If you check out the picture I attached you'll see that the functions are all the…
Since wire color codes are NOT universal, we always recommend wiring by function, rather than wire color. If you look at the Trailer Wiring FAQ article I have linked you to, you can see some diagrams showing the proper way to wire a vehicle and…
Yes, it will work. You'll just need to cut the Lance 6-pin connector out and rewire it into the etrailer Trailer Wiring 7-Way Upgrade Kit w/ Junction Box and RV Style Connector item #e99011. Here are the individual functions of that Lance 6-pin:…
In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.
Thanks for reaching out Robert, I did some digging and here's what I found. Optronics bracket #A65PB is a single wire design that grounds through the mounting hardware. I checked through Optronics for the 2 wire to find that it's been…
Welcome back Jordan! I have an alternative for you but we do not have any Ram 7k jacks that can be bolted on. Just welded like item #TJD-7000S and pipe mount like item #TJDP-7000S-B options. For a 7,000 lbs capacity square jack that can be bolted on,…
Hey Greg thanks for all the information! To add a 7-Way connector and brake controller to your 2023 Ford F-150 XLT, I recommend the Universal Installation Kit for Trailer Brake Controller item #ETBC7, the No-Drill Bracket item #C57202, and the Redarc…
In these days of customer "no service" I am usually disapointed when doing business with people I don't know. It was refreshing doing business with you. I'm impressed!
Dial in tidy connections with Optronics trailer wiring that's easy to work with on new builds or replacements. Pick 4-way flat setups for stop/turn/running lights, and remember a 4-pin won't power trailer brakes. Wishbone-style options simplify left/right runs without extra splices, and on aluminum or tilt decks, a dedicated ground wire to each light keeps everything working smoothly.
Run dedicated ground wires instead of relying on the aluminum frame. Tie each light's ground back to the main ground at the tongue. This helps prevent issues caused by poor grounding on aluminum structures.
Yes, Optronics wiring can work well with a wishbone layout. Test each wire's function before cutting so left and right runs are identified. A 4-pin flat provides left and right brake/turn and running lights only. Trailer brakes are not powered by a 4-pin connector.
Confirm the plug orientation before wiring. Some connectors include no documentation, so verify the pin layout as you go. Parts can be small and fiddly—work over a tarp to avoid losing them. Connections can be set up for bare wire or O and U shaped crimp terminals.
It can be a direct replacement if the pin configuration and mounting match. Some replacements have thicker wiring and sheath and may be a bit larger, so minor adjustment could be needed. For 7-way styles, check that the plug head fits your socket and support the cable to reduce wobble and loose connections.
