7 pin trailer plug

[dportem]

Hello all, I seem to be a disaster today. I looked through the other forums but came back lacking in information.

My 04 dutchstar 4025 has the 7 pin trailer plug

My toad is a nissan xterra manual that I want to tow 4 down.

The wiring kit that is recommended is the blue ox BX8869 to a 6 pin plug.

The blue ox coiled electrical BX88206 is a 7 pin from coach to 6 pin to toad.

If anyone can point me in the right direction for a proper pin diagram for the 6 pin toad I would be very appreciative.

The blue ox directions tell you what each wire is but they don't tell you into what hole they fall into in the 6 pin plug on the toad.

Thanks in advance. Josh

Thanks for the reply guys. I have those diagrams, and each one looks different. Work with me here because I'm a little slow and need a good shove.

7 pins on the coach and only six pins on the toad and I'm only using four.
I see the trailer 7 wire circuit picture, now my question is are all coaches the same 1 through 7 pin configuration?

Thanks, Josh

Newmar is standard.

If you look at the 6pin plug, on the back side (after you remove the weather shield) you will see each pin is labeled...GD for ground, RT for right turn, etc. I would imagine the 7pin plugs is set up the same way.

When my 6 pin plug on the Toad rusted, I replaced both plugs Pigtail, and Toad with a fourway plug. Just make sure the colors match,

Josh, Diagrams are great, but the sure fire way to determine the pattern is to use a tester. You can get one at Home depot for $10 to $20 and are easy to use.

Of the seven, you only need four: left signal, right signal, ground and tail lights. You can also use the hot wire from the coach to the charge the battery on your toad while driving. If you have a brake system you need a 6th wire.

It is really pretty easy to wire. Very logical.

Here is what I have on my 04. Newmar pre-wires the coach and leaves them under the dash.

I'd do away with the 6 pin altogether (you say you're only using the 4 wires) and for a few bucks by a simple 7 to four pin adapter that plugs right into the MH. For another couple bucks you can by the 4 wire harness with the plug already on the end, just cut off what you need and splice it into your toad harness. As one post has already suggested, just make sure you match the wire colors.

IIWM, I'd make even MORE sure that I matched the wire functions. Colors will vary from vendor to vendor, so it's best to ensure that the pins are matched by function or application from tow vehicle to towed vehicle.

I've never seen a commercially available 4 pin harness that didn't use the same four colors (green, yellow, brown and white). If you've seen something different I suspect someone made it up on their own. Of course I'm assuming what was used on the Nissan is not a home made loom.

I was speaking specifically of wiring upstream of the 7 pin connector. Different chassis builders and truck manufacturers use different color conventions (and some change from year to year ) for wiring the 7 pin connector. Therefore, trying to match color to color from the 7 pin to the 4 pin wiring is a low probability of success exercise.

Even with a commercial 7 to 4 pin adapter, I'd check the functions at the 4 pin harness just to be sure that no one has changed the wiring going into the 7 pin adapter so that it's no longer standard (it happens!!) 6 pin connectors used on many gooseneck trailers are even worse as far as adhering to a standard convention for pin placement/function is concerned.
