Help? 5 Pin Round Wiring

[Hot Rod]

Howdy all,  

I am happy to say that this is my first post though I have been checking out the site for some time.  I'm even more happy to say that soon I'll be picking up my first true bass boat.    I found so much great info here I was hoping someone may be able to help me with a question.

The boat trailer has a 5 pin round connector.  The 5 pin round socket for the vehicle only has numbers on it so I don't know which wire (running lights, left turn, right turn, brakes, back up) to connect in which order.  Does anyone know if there is a standard wiring set up for the 5 pin round.  Seems like there is a diagram on the web for every other connector type.

I suppose I could wait till I go pick up the boat to see which wire is where, but I'd like to have the truck all wired to go so I don't have to deal with it then.  The boat is a few hours away too.  I know which wires are which on the truck just not where to connect them on the connecting socket.  I talked to a couple of local RV dealers and they didn't know either.

the best thing to do is get rid of that set-up and go to something more standard so to speak,,,like a 7-way if you have ele. brakes or just a basic 4 flat...hope it helps :-/

Like said, get rid of it.  Not sure what your going to pull it with but most newer vehicles require a special cable harness that plugs into you existing wiring in the back to adapt it so seperate brake and turn signals  work with the single light system on the trailer.  These are going to have a four wire flat connector.  You can buy the round connectors with the four a four wire flat pigtail already wired so all you have to do is plug the two flats together and you vehicle is ready to go with a round connector.  I've seen seven pin rounds prewired for the flats but I've never noticed a five pin.   the only time you will need more than the standard four wire flat,  is if you're running electric brakes.

If you check, you may find the wiring diagram comes with the connector for the standard configuration.  However, that doesn't mean that's the way they wired the trailer when they did it'

Hey thanks guys for the insight and your help.  

Turns out it was all a misunderstanding.

I spoke with the boat dealer again today and finally got someone who knew what they were talking about.  Turns out it wasn't a five pin round like the salesman told me during two previous conversations.  It is a five pin flat.  The salesman thought it was called a 5 pin round because the terminals are round not the connector itself!  

With the 5 pin flat I'll know what wires to connect where since it is a standard set up.

Thanks again!
