Okay boys, what did he do wrong?

As I read this thread, I couldn't believe what I was reading. Two different wiring diagrams depending on the type of trailer? Talk about a situation where the left hand has no idea what the right hand is doing!

I've never had anything but bad experiences with the 7 blade connectors. They are such a poor design - the only great job it does is separating you from your money. I had to bungie cord every one to pull the socket/connector together to keep it from failing. I purchased quality connectors and plugs - spent a lot of money to try to make it work. Kept the contacts spotless, applied anti-corrosive, the whole nine yards.

Now that I no longer tow a fiver or any trailer with a 7 pin, I've replaced all of them over time with 6 pin round which is similar to the 7 pin commercial. I use the 6 pin for the flat-bed and utility trailers, and plug in an equally well designed 6 to 4 pin adapter for the 4 pin flat where necessary.

Now that I have a drawer full of 7 blade connectors/sockets, I thought about donating them... but I'd feel guilty passing this expensive junk on to someone else.

Sorry, but tens of millions of RV travel Trailers USE the CORRECT 7 pin Bargman Chris and I posted about. There is NO problem with the correct RV 7 pin connector. Either Female or the Male. There is ONLY the 7 pin that has NO orange wire. The BIG problem is this--- The Color code for the flat 4 pun used on Boat type trailers and cheap inexpensive utility trailers the LT/RT/Running color code is different from the 7 way RV wire code. I advise customers to remove the 4 way flat on their yow cars and boat trailers and install a 7 way RV Bsrgman. That means ALL correctly wired 7 ways on Trucks and utility(SUV's) will fit their equipment. The BIGGEST problem customers have and a BIG money maker for me is the people that allow installers to install those round 6 ways and 4 ways and they NEVER get the wire code correct. Doug

It was also news to me that "RV" 7-pin connectors spec different wiring colors. You refer to 4-pin not matching the RV colors. How about the fact that the 4-pin, 6-pin, 7-pin utility and 7-pin commercial/agricultural connectors all use yellow, red, brown for left turn, right turn and tail lights? It looks to me like whomever "invented" the RV colors got it wrong.

Regardless, it is what it is. At least the 7-pin functions are compatible by position. The current will flow regardless of the wire jacket color.

Also, what color code are the factory tow vehicles wired to, utility or RV? That's what matters for the OP's concern here anyway.

Many years ago I came across a flat 4-pin connector where the color ordering was different than every other I had seen. It got cut up and tossed.

Sorry, 4 wire flat is NEVER the same color code as the 7 way RV plug. Remember, this is a RV FORUM and ALL responses and wiring should be taken from the RV industry, NOT the utility/Boat/6 way plug industry. 4 Wire flat
Yellow is Left turn--reverse on 7 way RV trailers
Green is Right Turn---Running on 7 way RV trailers
Brown is Running -- Right turn on 7 way trailers
White is ground--SAME on RV 7 way trailers
DUE to this wiring color change, THAT is what causes so many miswired and problems when people try to use a 4 way flat to the RV trailer. That is why I advise to remove the 4 way flat on the trailer that has the 4 way flat and install the trailer end 7 way RV Bargman plug. Doug
