YOU are a lifesaver! "And when the headlights are on..." I've been beating my head against the wall trying to figure out why, when I splice in my running lights, they don't go on. NOBODY on KZbin mentions "headlights" rather than the "auto" lights. Glad I watched til the end. Thanks DF Jay

That, Dirt Farmer Jay, was so clear. I'm currently setting up a four wire having bought a seven to four wire adapter but now I know someday I can wire up for a seven wire and know what's what! The 12 V added power is intriguing and don't see me doing electric brakes or the back up lights but now I know! Thank you for the video, Jay.

i have 3 grounding spots on each of my two utility trailers. I also had problems with the trailer lights once. I was sure it was a trailer side problem. it turned out to be the wiring harness I purchased that plugs into the rear wiring harness in the tow vehicle.

So the 4-way ones do not show brake lights when the towing vehicle uses them? Only the 7-way one does?
@DirtFarmerJay10 ай бұрын
Hmmm. I'm sorry I gave that impression. All versions of the wiring harnesses will always have a brake light function wired in to them. Best, DFJ

Yes the 5 way plug has the brake lights just like the 7 way, the 7 way has extra options for trailer brakes and an even a extra terminal that can be used for back up light, or camera power.

@@dogpatchfab -- There's 3 types of plugs -- 7-way, 5-way, and 4-way... My understanding of the 4-way is that it does not have a separate brake light, but if wired correctly on the vehicle side, it kind of simulates it by using the using the tail lights (brown) while also lighting up both tail lights (yellow and green) at the same time... I'm needing to rewire my trailer and put new lights on it because my dog ate my trailer lights and wiring... Yeah, I know, it sounds like the excuse a kid would have for not having his homework for the teacher ("My dog ate my homework"), but it really is true... The crazy ass dog liked the taste of plastic and chewed up the lights and then started on the wiring... So, I need to replace ALL of it... I don't even have the original 4 or 5 pin connector (it happened a couple of years ago and I am just getting around to doing it)... Yeah, procrastination... I'm damned good at it... I'm planning on wiring everything up to a 7-position box on the trailer tongue and then creating shorter cables for 4, 5, and 7 pin connectors... If I do it right, anything I might need to change would be a simple matter of moving cables around in the connection box... I'm also going to be using some square steel tubing to run the wires, just in case the dog I have now develops a tastes for electrical wires...

my advice - each component (light) in a Direct Current wiring harness should have it's own ground. In other words, do NOT use the ground wire from "Component A" to power "Component B". If you only have one wire (1 brown wire, for example) but want to power another light, use a 3-way splitter that splits that single wire into 2 wires. Then, each light should either be grounded to the frame of the trailer or wired back to the white wire, coming from the plug. If you have a light that is dim but not flickering, it might be wired in a grounding, daisy-chain where both lights are using a common ground. Hope this helps!

Howdy, Good video, have one question sir ; 2 wires for 1 plug on the flat 4-way. My lites work fine...except...break and all 4 bulbs come on Meaning mash the breaks turn & break lite up. Turn either way using signal, break turn lite up. Still with me.?
@DirtFarmerJay8 ай бұрын
I think I follow you. The first place to check is to assure you have a good ground THROUGHOUT the system. That means the ground on the vehicle, the connection to the connector from the vehicle, the connection to the connector from the trailer side, and the connection to the trailer frame. You really need to inspect all 4 points closely to assure there is connection. If there is a break anywhere at these 4 points, then they system will "find ground" in some really befuddling ways. Do the check, correct any problems, and come back to me. If the issue still exists, we can go from there. Best, DFJ

Just as long as the white wire is securely attached to the metal frame on both sides of the plug/harness, it will work. I like to put that attachment in a sheltered place to it doesn't get scraped or abraded. I hope this helps! Best, DFJ

@DirtFarmerJay7 ай бұрын
I've learned from experience that if we go into long detail, in this case, showing me pull wire through opening and such, that the majority of people will have their intelligence insulted and that I was too basic. So, we tend to stick to what isn't so intuitive. Thanks for weighing in and stopping by. Best Regards, DFJ
@garreth6293 ай бұрын
Some of us who have done a decent amount of DIY projects just want a quick rundown on what wire goes where. I'm rewiring a couple of trailers that have chewed up wires that are really dirty. Plus, you never know if they were wired correctly by the last person. It's really nice to have this to that rule. While an in-depth guide is great for some people, some of us don't want to fast forward through a half-hour plus video to find the segment we need. Both are helpful to have, but this quick video is exactly what I needed. Thanks

Tail lights are break lights ?
@DirtFarmerJay3 ай бұрын
Nope, indeed they are separate filaments or even bulbs. Tail lights stay on ongoing at dusk and through the night when the vehicle is in operation, brake lights come on, night or day, when the brakes are applied. Best, DFJ
