Umbilical and 7 Pin adaptor issues

[azflycaster]

Alan, I seem to remember a post or two about a master towing fuse that may or not be installed by the factory. I also remember about a fuse box located under the glove box. I could be all wrong here, but I would look foir something like that. Good luck

I saw something on the F150 forums about that but it did not elaborate. Looks like Ford dealer time? I also see a grouping of wires with nothing attached to them under the dash right near the brake controller plug, lableled something to do with power, but not very readable. Thanks Richard for your input ...

The flat is 20A rated, where the round is 30A, sometimes 35A rated. That's a 33% increase in amperage.
For those the have 12V fridges and electric/hydraulic brakes, the 7-pin round is a must have.
It is still a good idea to carry an adapter from 7-pin flat to 7-pin round, in case someone with a standard connector ( which sadly is a 7-pin flat) needs to rescue you.

Uwe & Andy -- I'm so glad I read your posts about the round pin connectors, because when I went to a trailer supply place today to buy a truck-side connector to go with the round pin connector on the Caravel, the guy spent 5 minutes trying to convince me that I did NOT want a round pin: they were far inferior to the blades, corrode way too easily, you have to saw them off after they corrode, I definitely need to switch to the blade type, blah blah blah. I just smiled, thanked him for his time, bought a round pin connector, and left.

Keep in mind that these two very useful fluids perform different tasks well. "WD" stands for Water Displacing, and leaves a protective residue. Good for protecting tools and rustable metal, but the residue is only a lubricant until it dries. Then it's gummy until it's sprayed again. LPS is great for improving electrical conductivity, as in contact points, and connectors. Compounds like spray silicone improve sliding coefficients, and are properly used to coat table saw decks, or jig saws. That's why it takes a large cabinet to store all the "spray-ons." There is no single product that does more than one, maybe two, tasks well. jsutro

Do they make a flat to round adapter and if so wouldn't one still need to rewire as stated in earlier post? I just called a RV place for this exact adapter and he couldn't find one (could be he wasn't looking in the right place though!) Let me know if they make one. Thanks!

I've never seen one but they are easy to make.

I use the six pin round, which has the same advantages as the 7 pin round and works fine if you're willing to give up the backup lights. Adapters from that to 7 pin flat are readily available.

Here is a 7-way flat to round adapter. This works well for the standard flat blade tow vehicle receptacle to round trailer plug.

OK if I read this right I can get the 7 flat ot 7 round pigtail set up above and plug it into a late model factory wired 7 flat and it will work on a 7 round Airstream 76 model?

Seems too good to be true

Thanks much.

Thanks Jammer. I just decided to rewire the existing, which was a bit of a head scratcher to figure out but finally got . And I don't think an adapter would have worked straight out of the box anyway without the rewire. Things sure have changed since 1969!
