Yakima bike rack lights

[John and Debbie]

Does anyone have an idea how to form a flat four way connector from the licence plate light wires on the back of the Ollie?  The tv has the four-way connector as well as the seven pin connector.  We're going in for service on October 30 and I mounted the light kit on the Yakima Stage 2 bike rack.  I am guessing that the license plate lighting would not have the capability to power the brake, turning, and hazard lights.  OTT will look at the wiring needed.  Somehow I am guessing they'll need to run a 4-way from the tv to the back of the trailer to enable the light kit to do all the normal functions.  Has anyone else done something similar?  Does the wire go underneath from the hitch to the bumper?  Does it somehow go between the hulls?  TIA, John

John, rather than splice into trailer wiring, the previous owner of our trailer ran a second circuit from the tow vehicle to the back of the Oliver.  It’s for the storage box on the back, and there is a quick disconnect for the box.  Wiring is under the hull.

There is a down side to this approach, both he and I had to cut an opening into the door of the TV 4 pin to connect the new flat four circuit. I’m probably going to build a new jumper that comes off the TV 7 pin, and splits to a 7 and 4 so I can better weather protect the TV connection.   If you would like, I can take photos for you.

That is a correct guess.

The PO of our rig "sloppily" ran a 4-pin circuit underneath the OTT from the hitch to the bumper for bike rack lights - effective, but not a sanitary modification and we removed it.

FYI:  You can access the OTT 7-pin harness from inside the "garage" after removing the floor - easy to do.  If you don't mind installing a "Clam" fitting or an Anderson connection - you can run your wiring through the hulls.  We did this on our's to install additional LED lighting under our 1UP bike rack.

You can find that post by clicking:  LED Light Bar on Bumper...  It follows @john e Davies instructions noted in Steve's post below.

Good luck, amigo.

John, this might help. I plan to do this, as I have the license plate relocation kit for the 1UP. It includes turn signals/brakes as well as the license plate light. Another one of John's gems.

I have installed this 4 four pin accessory connector in-line and just before the 7pin socket. I don't have a part number but I bought it at a local trailer supply. It is unplug, plug and play. This modification gives you a additional flat 4 pin connector on a pigtail which can be used when the 7pin socket is occupied (since the use of the 7pin often blocks the access to the integrated 4pin socket).   As I recall it was less than $30

@Mountainman198, that is great!  I need to do some research to find one for my F350.

Edit:  I just spoke to eTrailer, and it looks like this may be a simple option.

Yes please.  OTT will be doing the work since they know a lot more than me about wiring.  I am in the information gathering stage to hopefully get the best solution.

John, since OTT is doing the work, I don’t think you’ll have any problems at all.  They’re going to do a professional job.

I’ll try and get photos of my installation tomorrow.

Hey, @Steve Morris: please keep us posted on how that plate light option offered by 1UP works out; we're thinking about doing the same because the rack pretty much lives on the back of "Casablanca."

Thanks!

Will do! It probably won't be until after our early October Tearjerkers outing, though.

Ah!  No worries, TKX!

Not much to see here, but as promised, here are a couple of photos.  The first is obvious, the second is the storage box quick disconnect at the back of our Ollie.

It took a bit of chasing, but I did find the inline T harness to 4 pin that @Mountainman198 mentioned.  This appears to be a much better solution when compared to poking a hole through the protective cover of the factory connector.

Thanks.  I will run this by service to see if I need to buy this for the wiring job.
