Bargman Plug

[Norm Roy]

I checked the Document Center for the correct way to wire the 7 pin bargman plug.
I shows the Car End & the Trailer End.
I then checked the Car End in my van, and it is wired exactly like the Trailer End from the Document Center. In other words, it is reversed (mirrored) from that shown.
Can someone confirm that the Document Center diagram is the correct way to wire this plug.
Thanks,

Norm

Oh so that big round 7 pin plug is called a Bargman Plug??

The big round-bodied plug with six flat electical connectors surrounding a round centre pin is often referred to by the company which introduced it (Bargman), but they're not the only ones who make it now, and Bargman makes all sorts of plugs. It is also called an "RV" style 7-pin (or 7-pole) plug, to distinguish it from the type of 7-pin plug used on commerical truck trailers. Bargman themselves just call it a 7-way connector; they don't sell the truck-style 7-way.

The following diagram is clipped from the Dexter catalog. It shows both the 7-pin and (rare) 9-pin connector, but I didn't want to cut off the caption...




The 7-pin diagram agrees with the one in the FiberglassRV Document Center, but I think it is important to note that they are shown from different sides of the receptacle. The Dexter view is looking at the contacts where the plug goes; the one in the Document Center is looking at the other side where the wires attach: so they are mirror images of each other.

I assume both are right, as I have yet to find a published diagram for this connector which is not consistent with all the others (a good reason to use this style of connector, in my book...). I have been caught by the mirror-image problem, though.

Thanks Brian, the Dexter catalog diagram is exactly the way my van plug is wired.
