Video Transcript for Complete Breakdown of the etrailer 7-Way RV Style Connector with Molded Cable

Jeff: Hello everybody, this is Jeff at etrailer.com. Today we're going to take a look at the six-foot long 7-Way RV Style Connector with the molded cable for your trailer end. Now, this is a pre-wired seven-way blade style trailer end connector that'll let you connect your trailer to your vehicle. This will replace a damaged seven-way RV style trailer end connector.It has a nice flexible cable, so it allows for easy positioning. And it is a molded cable. The covering insulates and protects the wires from the elements.

You'll notice it has the nice finger grip for easy connect and disconnect of the cable to your seven-way socket. And this wire does meet the SAE standards.It's a very simple installation. On this end, you just hardwire this to your existing trailer wiring. And the wiring codes they use are RV standard. So basically the white wire here is for ground.

That's a 10 gauge size. The black is for the 12 volt power, which is a 10 gauge size. The blue wire right here is for electric brakes, 12 gauge size. And then the other four remaining ones are all 14 gauge size. The green is for the tail lights.

Yellow is for aux or reverse lights. The brown is for right turn and stop. And the red is for left turn and stop. Again, the cable length on this is six feet. But that should do it for the review on the etrailer six-foot long 7-Way RV Style Connector with the molded cable for your trailer end..

Perfect fit, easy to install. Made the extremely annoying issues with power cutoff on the Cybertruck, caused by corroded old plug, completely go away. [and yes,, the Cybertruck has a stupid digital controller that if it sees an issue, cuts off the trailer power completely, leaving you with no lights in the dark…]

Glad we could help, John! What are you towing?

by:
If it had pre soldered connectors that would be a 5 star
by:
Very high quality trailer whip. I like how the plug is sealed tightly to the cable. It appears to be water tight. Makes swapping out damaged cables very easy, when connected into a junction box. I like to preserve the contact finish by spraying with a battery protector product yearly. My only complaint is the cable gets very stiff in the cold.
by:
Fast shipping,knowledgeable staff and good quality products
by:
I can always count on e trailer to have the product needed.

@James They might get older, but they will always need our help =) Glad you were able to get this installed on your daughters horse trailer. Does she go to a lot of shows?
by:
Great quality & shipping. Highly recommended
by:
Ordered Friday and had the part by Monday without paying for expedited shipping. The new wire harness colors matched my previous harness exactly. Install was very easy, will take the trailer out later to test the harness and my wiring. Overall very simple/quality replacement if you have a damaged wire harness
by:
Good quality and easy to install.
by:
The wire colours don’t match the standard 7 Pin Wiring Diagrams.
by:
Well made and less expensive than competitors. The wire colors are industry standard. The length is plenty and any longer would be a waste.
by:
Dont understand why the wire color did not match the standard trailer colors. Yes it came with a wire drawing but why not standard?

Great condition. I was hoping that there would be a code identifying each wires function.

  • Availability Of 7-Way Cable To Connect Truck To Slide In Camper
    Hey Mark, welcome back! We don't have a 7-way cable with a male plug on both ends, but it is easy to make one. All you need is the etrailer 7-Way RV Style Connector with Molded Cable # e99010 and the 7-Way Round RV Style Trailer Connector # A7WCB. Cut the cable down to the length you need, install the other 7-way connector, and you're ready to go. What kind of camper do you have?

  • Parts Needed To Convert An EZ Loader Boat Trailer From Surge To Electric Brakes
    Hi Cindy, Are you wanting to transition to electric drum brakes or would you just like to switch to an electric-over-hydraulic (EOH) setup that you'd be able to use a brake controller? If you want to switch to electric drum brakes you'll need to know the axle capacity and bearing/grease seal combination for your spindle. You'll need to switch to electric drum brake assemblies, use hub/drum assemblies, will need a 7-way cable # e99010 and junction box # e99009, breakaway battery and...

  • Replacement Wiring for a Palomino B-1200 Truck Bed Camper
    Hey Guy, I wasn't able to pin down what exact wiring came on your Palomino camper, but generally the in-bed truck campers use a 7-Way so they are able to provide power to all of the lights as well as any power that the camper requires to operate. To replace a 7-Way you can use the Replacement Connector # e99010 along with Butt Connectors # DW05744-5 and # DW05745-5 to get all of your wiring connected. You'll want to connect the wires by function as opposed to by color. Let me know if...

  • What Wire Is Needed To Add Electric Drum Brake Assemblies To A Trailer
    Hey Jared, When installing electric trailer brake assemblies you'll want to run 10 gauge wire # 10-1-1 from the junction box back to the brake assemblies. This will be you power to the brake assemblies and you can just run the other wire from the assemblies to the frame with a ring terminal # 44-5310A and self-tapping screw for ground. If your trailer doesn't already have a junction box # e99009 and 7-way cable # e99010 then you'll want to pick those up as well. I've attached a help...

  • Do Electric Trailer Brakes Need 10 Gauge Or 12 Gauge Wiring?
    Hi Shawn! Trailer brake wire is typically 10 or 12 gauge, but either will honestly work. The 7-Way RV Style Connector with Molded Cable - Trailer End - 6' Long - RV Standard # e99010 is made for us (not in-house) and uses 12 gauge for the brake wire (blue), and we cannot change that, unfortunately. However, you could use the following two options to make your own 7-Way for your trailer: Spectro Jacketed ABS Trailer Cable Per Foot # SWC89FR Optronics 7-Way Round RV Style Trailer Connector...

  • What Gauge Wires are Used Epicord 7-way Connector part # e99010
    Hello Ralh, The etrailer 7-Way RV Style Connector with Molded Cable - Trailer End - 6' Long - RV Standard # e99010 has three different gauge wires in the cable. There are two 10 Gauge wires (black/white) there is one 12 gauge wire (blue) then there are four 14 gauge wires (yellow, green, brown, and red). These sizes are typical of most 7-way trailer end connectors.

  • Adding Brakes to 2024 Master Tow model 77T
    Hi Thomas; does the 2024 Master Tow model 77T have brake flanges on it? Assuming it does, you will also have to identify the spindles/bearings it uses. If it doesn't, you will have to add a brake flange. I would check with the manufacturer to make sure this is approved. If it is set up for brakes it is probably a 4-bolt brake flange. If I had to guess, it also likely has a #84 spindle with # L68149 inner and # L44649 outer bearings. Assuming that is correct, you can use the Trailer Hub...
