Thank you for keeping it simple. I have seen some videos make this operation the whole mole hill and then some. Thanks again.
You are very welcome and thank you for your kind comments!!!
Do you need anything further from me now Paul...?@@PaulsOutdoorAcademy
Thank you so much. You’re an excellent teacher and your demonstration was spot on! I especially loved your clarification of southern slang. Being from Oklahoma, I had no problem understanding them there words. Ha ha.
That’s awesome!!!! Thank you for your kind words!
Thanks to this video I was able to fix my wiring in less than five minutes! Thank you! 👍
Fantastic. Thank you very much for the comments!!!

Thank you very much!
Great video, thank you very much!
You are extremely welcome and I hope
I can create more content you can use.
Great video nicely done thank you
Thank you very much
So you loved the cradle but elected not to use it..😀. Great vid
Thank you. I liked it but wondered if it was worth drilling the holes in the frame. I left it out in the end and to this day just droop the plug over the trailer tongue hahahahhaha. Thank you for the compliment 😃
Paul, could I swap out my 4 pin connector to a 7 pin connector, and add an additional wire from that 12v trickle/constant and run it back to the trailer I’m building for a power wash/soft wash trailer I’m building to power a noco battery maintainer/charger? I’d like to run some lights off the battery
Sure can. As long as the vehicle plug supports it. 😉
You do a great job of videos, None better, I believe. So Thanks for that, but I have a problem and I and I am sure there is plenty of others also in my predicament, want you to do a video of taking the 4 wire on the trailer and hook it to the HOPKINS 7 Pin Plug with a Pigtail and all the Colored wire dangling from it to connect to the trailers 4 wire system. I have electric brakes on my Utility Farm Trailer dual axle.I await your great Video of this as for one thing the clarity of your videos as well as the expertise you exhibit with such great confidence as you work. I appreciate that in a man doing a video or job or whatever. Thanks....I am in a bind right now and if you could slip this one in fairly quick would appreciate it.
I would love to do it for you but I need to fully understand what you are asking for. I found the Hopkins 7 blade with long pigtail. Do you have the breakaway box with battery on the trailer?
I will create a video for you, but I need to know which hopkins pigtail you have, and whether or not you have a break away box on your trailer that needs to get wired into the mix.
You said you have a 4 way trailer side connector, but your trailer has brakes. I think you saying your towing vehicle has the round 7-blade connector on the back, your trailer has the 4-way connector, and you have a 7-way blade type connector with a pigtail, and you want to cut off the 4-way and wire the pigtail into it. If you can confirm this, I will get you a video quickly. :)
Just replied Paul to prior reply from you. Doug Styers...@@PaulsOutdoorAcademy
This reply is the only one I see. Can you reply to this with your answers?
Yes Sir, I just have the wires no plug on it now. Elec. Brakes. No Brake aways boxes etc. at alll. Hopkins Plug with a 4 ft. cable already wired into the plug when bought Paul. I need to know how to make the 4 wires connect up to the seven wires and everything work, including the elec. Brakes if at all possible Paul. Thank you Sir !

Hi great video however my running lights not on everything else is fine??
I need to do a video on that. Check your ground first thing. This is 90% of the issue usually. Make sure the light is attached to the frame and the screws on the light are making contact on the frame
What gauge for trailer wire? I'm thankful for the video!¡!!
It's an bass tracker 175 pro guide
It’s not that large of a wire. I am surprised it isn’t bigger. 16/18 etc 14 gauge is good for longer trailers or perhaps trailers with brakes.
Thank you for watching 😎
When I plugged it into the truck it doesn't do nothing ,I've checked the lights they all work.do I need to ground the center rod?
That center rod is not a ground unless your vehicle is wired in a non standard way. Is your round plug on the towing vehicle from the factory? If so, can you tell me the year and model of vehicle so I can look it up?
Thanks bro. Bought a boat and was wtf is this connection.
hahahah Happens to all of us. the good ol 4-pin used to be the law of the land.... then comes along 5, then 7, etc. I don't know what's next, but 7 has been the standard for a longggg time, at least on larger vehicles.
I recently bought a used camper for my truck, the campers cannection is a 7 pin blade (female) and truck has a 4 pin flat(male). I bought the adapter for it but for some reason the turn signals run opposite from each other. How can i fix it?? Please help me.
It sounds to me like you are saying you are using an adapter for the entire connection, and you didn’t do any of the wiring yourself. If this is the case you have a couple options. Probably the easiest way to fix this would be to swap the green and brown wire on camper side. If that is not an option, I would check to see if the wiring on the truck side is correct. Do you have a 12 volt test light or voltmeter?
@albertoleon5910, If I were troubleshooting this, I would want to know what the issue is. I would use a voltmeter on the truck first. Put the left turn signal on in the truck and then probe the ground and left turn male pin on the truck. Left turn should be Yellow, and It should blink or show voltage jumping up and dropping, etc. if it does not, keep the probe on ground, but then switch the other probe to the green male pin. if it is flashing, the issue is on the Truck side and you need to go under the truck and reverse the green and yellow. If the truck side all looks correct, the issue is on the camper side.
hello paul ! i have a 4 pin ( us ) trailer plug on my car ( brake and turn signals on combined ) , but the trailes has 7 pin ( eu ) plug . i have one curt adapter frome 4 to 7 but it doesn t work ( still brake and turn combined and no tail lights ( it only lights number plate ) any solution to rewire the 7 pin plug , or to split brakes frome turning lights ?! thank you
What color are the wires on the vehicle side?
@@PaulsOutdoorAcademy green, yellow, brown and white
Ok I found a good diagram with pin outs for the 7 way EU. This should help

Nice video! I have a question for you. My existing 4 pin connector has 7 wires ( yellow, green, white, off white, black/ yellow, black/green and black/white wires) can you help me?
I will try my best. I will look that wiring up as I have never seen a four way connector with 7 wires. Is it really old?
Can you email me a photo at the connector so I can see what it looks like and how the colored wires come out of it ?
@PaulsOutdoorAcademy it is a old connector and yes I can email you. What's your email address?
@@PaulsOutdoorAcademy I was able to get it the 7 pin connector installed and all checked out and is GTG Thanks!!
Thank you for the follow up. Awesome!!!
So if I added a blue wire, so I can have Trailer breaks, where does it connect? Jeep wrangler JL 2018?
Howdy and that’s a good question but I need more info. Does your jeep have a 7 pin trailer connection already?

This should help
@@PaulsOutdoorAcademy I have a 4 pin connected now, but I’m trying to add a 7 pin
Mainly just the breaks, I have a trailer
with battery/electric breaks.
@@motivationalworld345 ok, so your best option is to see if you can find a wiring harness specifically for your jeep. If this fits, it would be a good option:
