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! :-) 811282

Received ten in good order. Appears to be heavy duty and very well made. Round plug fits well, as it should. I have not used it yet but don't expect any issues with it. Will follow up when used. 781827

Exactly as described, coverts 7 pin to 5 pin for allowing trailer back-up light connection when utilizing hydraulic surge brakes. 763613

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. 756879

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. 543841

Product IS as promised! Quality is good and the shipping fast. Wish I would've simply looked here to begin with. My 4runner has the plugin for a trailer way up and away from the trailer tongue and this adapter done the trick. 542088

Ask the Experts about this Wesbar Wiring

  • How to Use the Coiled Adapter 7-Way to 5-Flat Part # 787207 with a Reverse Lockout Solenoid
    I 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.

  • What are Pin Functions of 5-Way End on Wesbar Adapter # 787207
    When 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...

  • 7-Way to 5-Way Extension Adapter for Boat with Surge Brakes
    Actually 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.

  • 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...

  • Dimensions of Wesbar Coiled Adapter 7-Way Flat Pin Blade to 5-Flat
    The Coiled Adapter 7-Way Flat Pin Blade to 5-Flat # 787207 cord has a 0.35" diameter and the coiled section is 5.5" long. I have attached a photo demonstrating this.

  • Old Trailer Wiring 5-Way had 6 Wires But New 5-Way Has 5 Wires
    The 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...

  • Recommended Way to Re-Wire a Boat Trailer with a 7-Way Plug
    The 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...

  • 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 Brakes
    The 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 Camper
    It 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...

  • Towing Triton Bass Boat Behind 2017 Ram 1500 Short Bed with Lance 650 Truck Bed Camper
    In order to tow your Triton boat behind your 2017 Ram 1500 with the Lance 650 on board, you need a Class V hitch like the Curt # C15572 . 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...

  • Availability of Flat Towing Umbilical Cable Longer Than 3 Feet in Length
    We do offer some longer coiled cables that would work for you. 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.
