    Replacement 5 way flat light adapter for a Ranger trailer
from VonH #13973

 Buggered up the adapter on my buddys ranger trailer. The strange part is the adapter is a 5 way flat, but has 7 wires coming out of the back. I havent been able to find one.

Wesbar doesnt show one on their website, or at least I couldnt find it.

Any part numbers, leads, etc would be great. I dont really want to order it from Ranger.....

   I think if I ever have to replace mine from Skipper  6/14/2011 9:10:56 AM
 I'd me apt to replace it with a 7 pin round connector. That is the standard on most vehicle hitches. That 5 pin flat has outlived it's usefulness.

   the extra wires from MikeF  6/14/2011 9:26:37 AM
 It's a 5 pin connector. The two extra wires are because you have a wire for the brake lights running down both sides of the trailer and the same with the running lights. You can buy any quality 5 way and splice it back in. I assume Ranger uses the standard color coding so it should be easy to figure out which wires are which.

 I love the Flat 5 connector and cannot see doing without it. I have my vehicle connector going from it to a flat 5, I can easily connect to a flat 4 if I tow somebody without backup lights on their trailer. the person who said to use a round 7 pin is absolutely wrong... Any autoparts store has them, I bought mine at Autozone.

   Wesbar does make a 5 way from spinerb  6/14/2011 3:42:29 PM
 Have used them on several boats and usually get them at most auto parts stores. All marine stores carry them good Luck Walt

   MikeF from VonH #13973  6/14/2011 6:14:30 PM
 So, it wont matter if I splice the 2 brake leads into the one wire from the connector? Same for the 2 tail light leads, into one lead from the connector?

   correct from MikeF  6/14/2011 9:20:31 PM
 That's how they are now but it's inside the plug.

   Thanx!!! from VonH #13973  6/15/2011 11:24:18 PM
 Thanx Mike F!!!

   You aren't going to have two brake light leads from the same pin from Catfan #10754  6/16/2011 10:29:24 PM
 Brake lights each have their own dedicated pin on the plug so they can work as turn signals.

   7 pin Round from Skipper  6/17/2011 11:23:54 AM

Just my opinion, but if all my tow vehicles come from the factory with a 7 pin plug on the hind end of the vehicle, It would make sense not to have to have adapters to every known configuration of trailer harness. I've got some with 5 pin round plugs, some with 5 pin flat, some with 4 pin flat and I have a box of adapters under my back seat. It's kinda like going in the auto parts store for an oil filter and there being a 7' tall by 20' wide shelf of assorted oil filters. It's unnecessary. 2 or 3 filters could probably do the same job as all those different ones.

It just seems to me that if the vehicle manufacturers have had the sense to standardize the trailer light hook up on the vehicle, why not standardize the trailers to match?

 It is the adapter for fifth wheel and gooseneck trailers that use the seven pins withvrake attachments. The four and five in flats can both be used with the five pin harness. Wesbar does make. A seven to five pin with a stub lead to reach the ball area for those leads to be shorter, otherwise they can drag.

   Campers and some flatbeds box trailers use the 7 pin like comes with most vehicles with tow packages from Skipper  6/19/2011 1:53:13 PM
 Just seems to me the vehicle manufacturers are settling on a standard for once. Remember when they had 50 of those t adapters to hook into the wiring harness of the various vehicles? Now there is a standard on the trucks but not the trailers

   Difference from STRETCH1 #11051  6/20/2011 2:43:42 PM
 I got a 2 year old GMC truck, my 7 pin connector is completely different than the connector on a new Ford Truck, also a fishing buddy of mine has a Honda truck and the connector on it is different once again. Seems like the only standard is the flat connector so get a connector for your vehicle that goes to a 5 pin flat and you are good with nearly every boat trailer on the market (5th wheel and camper trailers are different once again).

I too wish everything was standardized and do not see why they cannot be but I think the flat connector is cheap to install and fits every kind of adapter out there.

   flat five from Fishfighter #13439  6/20/2011 6:22:58 PM
 I would not replace the flat 5 with the round 7 pin. I have an adaptor for my Suburban from 7 to the flat five. If you need to pull your boat with another vehicle, they may not have a round 7 pin. And, if they have a flat 4, you can splice the wire from the backup light on the vehicle to the 5th pin.( I had to do this with my brothers truck)

   About $20.00 from Rangerman  6/23/2011 8:17:13 PM
 will cure your very miner problem. Std, round 7 pin on most trail package units to 5 pin, which also works the 4 pin can be purschased about any good trail hitch dealer or boat dealer for less than $20.00, or you can buy the round 7 pin and wire it to 5 pin for about $15.00

   If from Skipper  6/25/2011 8:00:40 AM
 The 7 pin round connectors were wired different from manufacturer to manufacturer then the commercially sold adapters you mentioned would be about as useful as buffalo poo.

I've got a dodge and a ford. Dad has a suburban. The same adapter works exactly the same on all 3. I've got 1 trailer with electric brakes and a 7 pin round connector. It works on all 3 if I have a brake controller in the vehicle.

Wired to the trailer correctly it shouldn't make any difference what make vehicle you are driving.

The only slight advantage to adapters is regulating the length of the trailer wire. On my dodge my 5 pin flat doesn't have wire out the end of it to the 5 pin flat. The whole thing is on he plug itself it works great on the dodge and the ford. On the suburban the plug is farther from the ball and it won't reach without the extra wire hanging out the adapter
