Good product. Had an issue until I coated connectors with dielectric grease. Now works flawlessly.

Just what I was looking for to maintain a consolidated connection between my boat trailer and truck. I will definitely check your site again if I need any future trailer supplies. Only other comment would be to have manufacturer offer it in black.

Recently bought a used boat and trailer and needed this connection for the lights to work. I wasn’t able to find it locally but Etrailer had a couple of choices in stock. Works perfectly, fast delivery.

Out standing product. This is easily one of the best trailer power extensions out there. Coils up back into smaller form factor after every use and stays firmly connected into the 7 pin or 5 pin connection without wiggle room. I use for my boat connection and you don't have to worry about the hair pin turns pulling on the electrical connection as the coil allows for that extra room. This cable is highly recommended for anyone with this type of connection.

by: Ron A.06/08/2016
This was just what I needed to hook up my trailer lights to my new vehicle! I needed to convert my 7 pin vehicle connector to my 4 pin trailer connector, plus I needed a little extra length for my trailer pigtail to reach the factory connector on the vehicle. The delivery was fast too! Thanks!

The trailer connector was competitively priced, shipped quickly and arrived on time. I tested it and it works just as advertised. I ordered a 4' long coiled adapter and that is what I received, but I should have ordered the longer version as the 4' long version is stretched pretty tight on my boat trailer to truck connection. But, that is my error and has no bearing on the product quality or etrailer.com. I would order again from this company. Keith Z.

TFX225 was good TX430-1 was good also p/n 787207 is not a 7 way pin to 5 flat, IT IS A 5 PIN TO A 5 FLAT, product didn't work. I initially thought it was a defective product but was told no by customer service that a 7 pin always has 2 dummy locations. Info was forwarded to Tech Service who called later that day stated the above and that my trailer shouldn't be working as I have stated it does. Four separate vehicles have towed my trailer and none have had an issue with it and the electric brakes work fine with the controller. It was strongly implied that I have messed with the trailer wiring, which I hadn't.
Comments
I believe I know what is going on. A basic 4-pole flat has the following 4 connections: ground, running lights, left turnbrake, and right turn/brake. A five pole flat either adds an electric brake circuit or reverse light circuit. The reverse light circuit is used quite a bit for boat trailers. They use hydraulic actuator brake systems and the reverse light signal is used to lock-out the brakes for backing down a boat ramp. This adapter is wired for reverse lights on the 5th pin, and your trailer is wired for electric brakes on the fifth pin. The center pin of the 7-way is used for reverse lights, not brakes. So the brakes on your trailer will engage when you put the vehicle into reverse.

The cord end look to be hi quality with the extra cord coiled for any stretch that is needed. The yellow cord is faded new out of the box and the coating is very tight this may not weather well, guess time will tell. Over all for the price seam to be a good product.
Comments
the product is working well

Can't really say much about the product itself other than it works as expected & is a fantastic design w/ the coiled cable. My main glowing recommendation is for etrailer itself, as I have received stellar customer service from time of order to receipt of product ordered. Very helpful, professional, personal(sized), & prompt. I couldn't ask for anything more from a company! Thank you, etrailer! :-)

Phone staff was very helpful and knowledgeable. While I had a good description of what was needed I was asked all the right questions to be sure that I got the correct part to suit my needs. Let's hope the trailer brakes don't come on in reverse any more. Thanks for your help.

Great product, give you a great connection and flexibility so one can keep the actual trailer wires short. So without this someone cannot connect to their vehicle.

Product works very well for my MasterCraft boat trailer. Well made and I do like the coil which keeps the long cable from drooping when in use.

Both items perfect as always. Hitch lock long enough for up to 3 plus inches if needed which is great and the 5 pin adapter in the coil makes it so handy you will want all your cords like it.

Ask the Experts about this Wesbar Wiring
- What are Pin Functions of 5-Way End on Wesbar Adapter # 787207When looking at the 5-Way end of the Wesbar Coiled Adapter # 787207 like you described, with the male pin being number 5, the pin functions are as follows: 1. Backup Light Circuit 2. Right Turn/Brake 3. Left Turn/Brake 4. Running/Tail 5. Ground With this in mind it definitely looks like something might be miswired on your setup. The first thing I recommend doing is testing the 7-Way on your RV in the same manner that you tested the 5-Way on the adapter. The functions should match...

- Recommended 5-way Connector To Replace Damaged 5-way Connector With Two White WiresI have an option for you, but we do not carry a 5-way connector that has two white wires. What I recommend is the # A40W5B which has the two brown running light wires, one green passenger turn signal and brake wire, one yellow driver side turn signal and brake wire, and a blue wire which is commonly used for a reverse lockout solenoid. You will need to cut the connector off the # A40W5B as far back as needed and match the colors. Since you have two ground wires you will need to cut...

- Recommended Way to Re-Wire a Boat Trailer with a 7-Way PlugThe adapter will work but it's more of a short term solution because of the potential corrosion issues in the future not to mention when you introduce additional connection points problems can arise. I would test the reverse lockout (purple or blue wire) with a circuit tester with the 7-Way center pin. If that works you are good. I would recommend rewiring the trailer with a 7-Way plug because it will prove to be more reliable than using an adapter. I would start with a trailer junction...
view full answer... - 7-Way to 5-Way Extension Adapter for Boat with Surge BrakesActually the part # 787207 that you mentioned would be the perfect solution for you to use. The 7-way of the adapter will plug into the 7-way of your truck and then the coiled extension will give you 4 feet of extra wire to attach to the 5-way of your trailer.
view full answer... - Old Trailer Wiring 5-Way had 6 Wires But New 5-Way Has 5 WiresThe trailer connector that you had is what is called a wishbone harness. It has 2 running light wires so you do not have to run a jumper wire for running lights from one side of the trailer to the other. Wesbar harness # W002290 is an example of a wishbone 5-Way. All you have to do is connect the 2 running light wires from the trailer wiring together and then to the brown wire on the new harness. Or, if you are replacing all the wiring, you would run a jumper wire from one side of the...
view full answer... - How to Use the Coiled Adapter 7-Way to 5-Flat Part # 787207 with a Reverse Lockout SolenoidI assume you are referring to the reverse lockout solenoid wire and if that is the case then you would need to wire or check that the trailer side trailer connector has this wire on the far left pin which you can see in the attached photo of the Coiled Adapter 7-Way Flat Pin Blade to 5-Flat part # 787207. This pin should then match up with the reverse light circuit on your vehicle's 7-way.

- Is There a Different Sized Plug Version of the Wesbar 787207?The simple answer to this is going to be no, because trailer connections adhere to an industry standard in order to ensure compatibility between different manufacturers and for end user convenience. Trailer connector adapters like the Wesbar # 787207 will be the same size as something like the Hopkins # HM47065 -they are all going to have the same dimensions assuming they're the same type of connections (7 flat, 4 or 5 blade, etc.). For these reasons, the 7 way end on the Wesbar # 787207...
view full answer... - How Many Wires Inside Wesbar Coiled 7-Way Flat Pin Blade to 5-Flat Adapter # 787207 The Wesbar Coiled 7-Way Flat Pin Blade to 5-Flat Adapter # 787207 actually has 5 wires. This adapter takes a trailer-side 7-way plug and mates it to a 5-pole flat connector. All 5 pins on the 5-pole are connected at the 7-way side but a 12V power feed and trailer brake circuit are NOT supported. Two pins on the 7-way are inactive. If you need 7-wire jacketed cable we offer Deka # DW04914-1 which is sold by the foot and that has no connectors included. Or if you need a 7-way with the...

- Will Coiled Adapter 7-Way to 5-Flat Adapter part # 787207 Work on a Boat Trailer with Surge BrakesThe Coiled Adapter 7-Way Flat Pin Blade to 5-Flat # 787207 WILL work for you as long as the reverse light circuit is active on the 7-way of your 2012 Toyota Tundra (it should work). The reviewer you referenced unfortunately was confused on what this product does. Since one end of this adapter only has 5 circuits then there is no way 7 circuits could possibly be carried through the adapter. Since you have surge brakes those additional 2 circuits would not be necessary for you since they...

- Recommended 2-1/2 Inch Trailer Hitch Extension and Wiring for Boat Trailer Behind In-Bed CamperIt sounds like you need about a fairly long extender and there unfortunately is not an extender that isn't also a reducer for your 2-1/2 inch hitch receiver. My recommendation is to use the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048 which has the same capacities as the similar Reese # RP45292 and then use a more cost effective option for your ball mount like the MaxxTow Adjustable 2-Ball Mount - 2" Hitch # MT70380. This will give you an adjustable...

Once you have the Class V hitch, you need an extender bar similar to the Hitch Extender # HE18 paired with an extended ball mount like the Hidden Hitch 15-3/4" Extended Ball Mount # 80232 in order to get the correct length clearance from the back of your camper. You'll also want to consider adding a wiring extension like the Wesbar Coiled Adapter...

Wesbar offers a 7-way to 5-pole coiled adapter, that will also work fine for a 4-pole. For a 4 foot length, use part # 787207. For an 8 foot length, use part # 787196.
