Winnebago 7 Pin Connector

My 03 Adventurer did not have power on that pin. I ran the line myself from the battery, to a fuse, then to the connector.

Thanks for the information but I can't make heads or tails out of wiring diagrams!

Does not matter. The 7pin wiring is on the GM chasis and Winnie does not have that on their website. Also their schematics are lacking for any real troubleshooting as alot of information is just not there.

Ignore any Ford comments as you are GM. Based on what the other GM person said theirs never worked either. I would look on the backside of the 7 pin connector and see if there is even a wire to it. If not you will need to provide yourself and add a fuse. You can get that information from one of your earlier posts on this subject. If there is a wire there you can try and chase it back to the source or get the GM manual out and hunt down the fuse location. It could be in the cab, engine compartment or other hidden area.

Ignore YOUR comments as Workhorse is NOT GM. Workhorse is(was) Workhorse and had no connection to GM at all. Most 7 ways on Motorhome chassis will not have power to the 12 volt charge pin and usually will not have the electric brake(blue wire) connected either. They will be stubbed off or open at the quick connect at the rear by the hitch. On Ford and GM trucks, you usually have to install a relay AND a fuse to power up the charge at the rear 7 way even if the 7 way was installed by Ford or GM. Doug

I am trying to set up a charging wire to my 2013 CRV. The pin on my connector is dead. based on the posts here and elsewhere, I am convinced it was never connected.

Just run this wire to the + side of my CRV battery with fuses at both ends?

That is exactly what I did with our 2006 Sunstar. There was no power to the pin. Found this out when the battery in the jeep went dead 2/3 of the way to Tulsa! Corrected the problem there by connecting to the Generator 12v feed. Our new Sunova came properly wired.

Jeff,
I believe the OP just wants 12VDC at the trailer plug on his/her coach. How "marker lights" and any other subject enters this, I'm not sure. But, this is a simple matter. All that has to be done is, what has been stated at least once is, climb under the coach, and see if there's even a wire that leads to that particular pin in the plug. There's two ways to go here. One, if there's a wire that leads to the pin and, it's dead with either the ignition on or off, then you can back trace that wire to the power source and find out what's the problem with no power.

And, the second way is, if there's no wire, then you'll have to set one up, from many possible sources on the coach. It's a simple chore.

Now, when you get power to that trailer plug, all that's needed from that point on is, run that power through the pig tail, into the toad, and up to the positive post on the CRV. And yes, do install a fuse for short circuit protection. There's no need for any "kits" of any kind. It's a charge wire, not brain surgery. Hope this helps some.

The trailer socket is installed by Winnebago. They bought the incomplete chassis from Workhorse and added a number of items including the socket.

You need to get under the motorhome and remove the wire loom from around the wires going to the trailer hitch socket. All the Winnebago installed wires will be yellow with the exception of 1 white ground wire. Each wire should have a series of numbers printed on them every 6-8 inches.

Here's an example of a wire to the trailer socket on our 2013 Adventurer.
149622-13-000(AE) AAD The last 3 digits are critical.

Copy down all the wire numbers and go to the Winnebago "Manuals and Diagrams" page: http://www.winnebagoind.com/resources/manuals/
http://www.winnebagoind.com/resources/manuals/

From there select "Wiring Diagrams" http://www.winnebagoind.com/diagram/Wiring.htm

Then select "Wiring Identification Guide": http://www.winnebagoind.com/diagram/electrical_guide.pdf

It's a 29 page PDF document listing all the wire numbers Winnebago has used for at least the last 20 years. It'll tell you What the Winnebago numbered wire is supposed to connect to on the chassis. It's alphabetical to make it easy to use.

Here's the example of the wire I mentioned earlier on our motorhome

AAD / 14 YEL FORD CHASSIS TRAILER MARKER LAMP CIRCUIT BR/WHT TRAILER CONNECTOR SOCKET MARKER LAMPS

The Red colored section (my addition) identifies the size color and pin the Winnebago wire is connected to at the trailer socket. The bold portion identifies the chassis wire it's attached to. I our case there is a label with that exact wording on wiring harness from Ford

Our Workhorse had no connection to the 12 Volt pin on the 7 way connector. I doubt that any of them were setup with the 12 Volt power on the connector. I simply ran a #10 wire fused with a 30 amp fuse from the 12 volt main pin on our rear mounted Onan genny. Works fine and keeps the toad charged without pulling any fuses.

-- On edit, having switched to a Volt on a dolly now I no longer need the 12 Volt for the toad. Such is life as things change constantly.... :) Love the Volt, but the dolly towing is a bit of a bother. :) I knew it would be a bother, but the Volt is worth the effort. Haven't bought any gas for it since I took delivery on 4/19/2013. That rocks.... :)
