7 Pin Waterproof Holder Mod -

[Galway Girl]

I’ve done a modification to add an Optronics 7-Way trailer harness plug protector.

 

Here’s the link to the part I used from e-trailer.(Including shipping and tax < $10

7 Way Plug Protector - by Optronics

 

 

And here’s where I mounted it…on the back of my Tongue Box.

I used stainless #10 bolts to mount the unit.

It could be mounted with zip ties to the bottom of the tongue as well if you don’t want to drill holes.

The cover is a semi rigid type of rubber material but with enough flex to make it easy to insert or remove with one hand.

 

In any case, I switched to this after my original “rubber cover” leaked.

@Galway Girl How has this Optronics 7 pin plug holder worked out?  I read some reviews that said it was hard to get the plug in the holder and some reviews that said that the “latch” wouldn’t hold the plug if mounted vertically.

I have not had a problem.

Ours is working fine. I used 3M VHB tape to mount it to the cargo box instead of bolts. I used the primer that 3M sells for the tape on both the plastic holder and the metal cargo box. It's been holding up quite well  thus far. It is a nice low-stakes test of using VHB tape on the outside and w/o any caulking to protect it - 3M says this is usable "indoors or outdoor" and that it "Creates a permanent seal against water, moisture and more."

We haven't had either issue (and  ours is indeed mounter vertically so as to make it tough for any water to get into the  open end of the plug)

Mine is mounted vertically also.  Keeps water out, and no problems with plug retention.

I have a 7 pin plug holder mount on the front of the storage box which I do not use. The previous owner told me a no cost option. Tuck the 7 pin plug in between the fiberglass shell in front of the propane tanks and the frame of the trailer (the fiberglass shell is the one you can see in FrankC's picture.) This location works great, the plug stays in place and no moisture or water gets into the plug.

Yep, had bugs living in my 7 pin plug . this was the catalyst for me to get a plug storage cover. this option is a no drill solution that installs with worm screws that tighten the bands around your front jack.  takes 5  minutes the install. its clean and works well

We bought one; attached it to the tongue (we don't have the storage basket) with zip ties, to see how it worked.  My husband doesn't like that the holder fills up with road dirt while traveling.  Unless you wash it out before storing the plug, the dirt transfers to the plug.  He thinks there are better ways to store the plug and protect it from the elements.

I can see where this would be a problem and I'm glad you pointed it out. Some of the time, I see these mounted the other way around and that is definitely a problem.

So the protective cover needs a protective cover. Hmmmm, this could go on forever...

[ThomB87]

Maybe because mind is attached to the basket and higher up than the tongue, but I have no issues with dirt or other debris when traveling.

We have yet to encounter that issue. Possibly having mounted it to the rear side of the storage tray rather than to the tongue has helped, or perhaps we'll see more of this when we spend more time on dirty wet roads.

The one that attaches to the jack post with plastic worm gear clamps is a great option for those who shudder with trepidation at the thought of drilling holes into their Ollie.

I have yet to drill a hole in mine, although I am certain the day will come sooner than later.

That’s the same one I have and I’ll second the recommendation.

This project I did in 2016 might have driven you to drinking.

We don't have the storage basket, so ours is mounted on the tongue.

I like this, but I'm afraid to add any more mods to the Honey-do list.

Indeed!

Nice work, @ScubaRx

[ThomB87]

Also beside a cover I use dielectric grease to keep moisture out of the plug. Should work on bugs too.
