Neat connector for trailer wiring

[Gary_in_Indiana]

I had one vehicle with a flat four connector I needed to upgrade to a six round to accomodate a larger trailer with brakes. Since I was also going to still use it for the smaller trailer and car dolly as well I figured I'd just get an adapter to use with those. While I was shopping for the new six round assembly and 6 to 4 adapter I came across a real neat connector for the truck.

It's a pre-wired six round and flat four side-by-side in a solid base I put right in my bumper. The best part was the flat four I already had just plugged in to the back of this covering three of the six connections I'd thought I was going to have to make myself. I had to run my two trailer brake lines and connect a separate ground and I was done. I didn't have to cut my existing flat four off and don't have to worry about an adapter, either.

Tomorrow I'm doing an upgrade to my upgrade on my trailer. I guy who does some work for me suggested this and I loved the idea. I'm replacing the round four connector on the rears of my trailer (yes, the brand new one I just installed Saturday) with a six round with just the four lights wired. I'm also changing the end on my magnetic towing lights to a six round wired the same way (yes, replacing the one I just installed Saturday to replace the flat four that came with it).

It's all going to be worth it, though as this way I can use the towing lights on the second vehicle towed behind the trailer AND with a vehicle on the tow dolly with the dolly plugged into the flat four connection on the bumper and the tow lights plugged in to the six round right next to it. Again, no adapters, no splitters, just plug it in and go. /w3tcompact/icons/smile.gif

Could not have said it better myself./w3tcompact/icons/smile.gif I have read through it a fews times, and I just can't picture it.[I'm a little slow sometimes] Picture would help alot./w3tcompact/icons/smile.gif

Geez, you guys obviously don't have a full appreciation for the process. /w3tcompact/icons/smile.gif Today I bought a couple round amber reflectors for the teardrop portion of my fenders. /w3tcompact/icons/shocked.gif This is the fun part for me. /w3tcompact/icons/grin.gif When I'm using it I'm working. /w3tcompact/icons/sad.gif

As to pictures, I'm assuming you've already seen the pictures I posted of the trailer itself and you'd like to see a picture of it loaded with two vehicles, right? I'll try to get that handled this weekend. Would you like step-by-step photos of the loading process or just one with it loaded?

I switched everything I have to the standard 7-wire RV connector. Everything hooks up easily, and all is wired exactly the same, by the spec(there is a spec for this stuff!)
I wired my old Ford for 7-wire, and my Dodge came prewired for 7-wire.

The 7-wire has turn signals, brakes, backup lights, charge line, ground, and running lights; it's all there.

The horse trailer, car trailer, and my old camper were all connected the same way.

I do have a couple adapters that I store in the rear under-seat that adapt 7-4, and 7-6 wire. I also have a pigtailfrom the seven wire, just in case.

So, all my stuff is standardized, and I can adapt to anything out there if I really have to.

That would be SAE J560.
1 WHT Ground
2 BLK Side marker
3 YEL Left Turn
4 RED Stop
5 GRN Right Turn
6 BRN Tail
7 BLU Auxiliary

Hey that "Censored" blanked out the word "[censored]".

Is that a swear word for you guys??

hang on, maybe it will go again. I used the word

D.A.M.N. - Is that bad or what??

Gary we want photos of the second car loaded with something on the trailer and your truck pulling it.

Can't wait!!

Cheers

The seven round is what we call an RV connector. The only wiring difference is the blue auxillery wire and I don't really have a need for that on anything I have or anticipate ever towing with my Tahoe. I still needed the two different connections on my bumper so I could use the two simultaneously. I can plug a car dolly flat four into the flat four portion and my towing lights into the six round for added safety and visibility. That's also why I converted the towing lights and the connection for them on the back of the trailer to a six round connection.

Neil, I don't know if the Senate Watergate hearings made it on TV down your way in the seventies but ever since then we Americans prefer "[expletive deleted]" to "[censored]" in such situations. /w3tcompact/icons/smile.gif

Since you're ordering up pictures here, what would you prefer as a tow vehicle? The options are my Tahoe (kind of my everyday driver), my ugly municipal orange Ford F-Super Duty dump truck I'm reworking to be my farm truck or my single axle Pete?

Now for the hauled and towed vehicles. Any preferences there? I could load my Deere and tow a truck or load one truck and tow another. Even though most people would call this trailer a car hauler, to paraphrase that famous line from 'The Treasue of Sierra Madre' film, "We don't have no steenking cars." /w3tcompact/icons/laugh.gif/w3tcompact/icons/laugh.gif/w3tcompact/icons/laugh.gif

Before you get too excited placing your custom photo orders here, let me tell you it could just be of whatever's most convenient at the time. /w3tcompact/icons/grin.gif/w3tcompact/icons/tongue.gif/w3tcompact/icons/laugh.gif

Well I think it would be awfully (expletive deleted) conveinent at the time. If you could load show the Pete towing the trailer with the veteren orange F450 on the trailer, with the JD in the bed, and the Tahoe. on the tow swivel.

Or was it the JD towing the trailer with the F450 hauling the Tahoe, and the Pete on the back.

If I can order photos............

I'd like the biggest, heaviest vehicles you have to do the towing and be towed. As long as it is within your laws and towing limits.

(I assume to tow a truck on a trailer and another behind that you must have a BIG tow vehicle)

Our towing laws allow towing of 1 or 1.5 times the weight of the tow vehicle TOTAL.

If you are going to show us up, better do it in style.

Cheers

That standard does not look familiar to me./w3tcompact/icons/hmm.gif The side markers should be on the same wire as the tail lights, the stop lights are included with the left and right turn, the blue wire is normally used for electric brakes, and there should be terminals for backup-lights and a battery connection. Maybe there are several different standards for these connections. I know the one you listed is way different than the ones that come with the 7 pin RV connectors I have connected.

 

[MJB]

I just did a little searching and came up with this: <A target="_blank" HREF=http://www.rverscorner.com/wiring/7pole.html>RV Trailer Wiring connection</A> This is the setup I am familiar with. It mentions that there is a different standard that the semi-trucks use. Maybe this is the one that was posted earlier.

 

[Wood_Butcher_Dav]

The Standard that I listed is for Truck-Trailer. This standard is also use on big farm tractors and implements or at least some of the green ones that I work with.

Cute, Russ... Actually, not only would I be over the limit of the trailer (it only has two 3500 lb. axles) but there's no way I could get the Deere to fit into the dump bed of the F-450. Nice try, though. /w3tcompact/icons/tongue.gif/w3tcompact/icons/smile.gif/w3tcompact/icons/laugh.gif

Neil,

I may not know the laws as well as I should but so far as I know I can load the trailer to the max and pull it legally with a Honda Civic so long as I'm properly lighted. I know this makes no logical sense, but, in the immortal words of Yakov Smirnov, "America. What a country!" /w3tcompact/icons/smile.gif

When I use my Tahoe to tow it's not uncommon at all for me to have a vehicle of equal or greater weight on the 2,000 pound trailer. If I'm towing heavy (one on the bed and one in tow) for a long distance I'd probably want something bigger than my Tahoe for the task. Tahoes are a shorter wheelbase class 1 4x4. I'm considering going to a class 2 Suburban K-2500 4x4 if I'm going to be moving two very often.

As to your request for a heavy towing vehicle, I can show a Peterbilt single axle but that's not what I would normally use at all.

For the fun of it, if a Honda Civic is legal, then go ahead and hook that baby up.

I want to show a picture titled "Laws gone silly"

I moved the trailer to the office back lot today but lost the light before I thought to load it for a picture. I'll try to get one taken Monday or Tuesday.
