Default convert trailer to 7 way wiring

I bought a new truck that has the 7 way round wiring connection and my trailer has the standard flat wiring connection. I need to rewire my trailer and was wondering where I can find a 7 way plug that I can tie directly to the wiring on my trailer instead of having to use a 7 way to 4 pin adapter all the time.

Try Portsmouth Trailer. The problem I see is if you ever want to use another vehicle to tow, you might not be able to hook up lights and brakes.

I'd leave it with the 4 flat and just use a 4 to 7 adaptor, for the reason above, many older trucks only have the 4 flat. My 07 Jeep has both, my 98 has only the 7, so I used the adaptor. Some newer trucks have the flat 4 coiled up in the wiring, take a look for it....

I replaced the entire pigtail (from the trailer to the truck) with one with a molded seven wire connector. I probably got it here:
http://www.easternmarine.com/
but I can't find it on their website. Give them a call, I'm sure they have it and can help you.

Adapters are just another place for loose or corroded connections and they can be lost or stolen.

This may be what you're looking for. If you don't have a Tractor Supply close enough to you just do a search for Hopkins, trailer end, 7 pin connector and order one online.

What you need is something from this page http://www.easternmarine.com/Trailer-Wiring-Adapters/ a 7 round pin socket, to a 4 pin adapter. No need to rewire anything.

you can get a converter that does 7 to 4 and 7 to 5 in one converter. Or just splice a 4 flat on the truck.

That would be what I used but I think I got it from the source I posted above.

Since around 1998 I have always cut the 4-way off and re-wired a 7-way round. Back then a buddy told me not to since most trucks (then) didn't have the 7-way connector. My answer was "good!" I don't want every truck in town to be able to tow my rig.

Portsmouth trailer will have them in your area but I've found them at Wally World too. They come with a diagram showing where to connect the wires.

When I sold my trailer boat, the broker called me that morning and told me the buyer was flying into town, renting a U Haul truck, and towing the boat to FL. He told me the trailer would have to have a 4 wire connection (not good since it had disc brakes). I made up a pigtail and was ready to wire it in but when the buyer and truck arrived, it was equipped for either a four wire flat or seven wire round plug so he was good to go.

Seven wire is where the industry seems to be headed.

Reading comprehension on this forum seems to be headed downhill fast.

Most never get past the subject line before responding.
