I Wired-In a New Harness and the Right Turn Signal & Brake Controller are Not Working Resolved

michaelroyy

I have a 2015 360s Boonedock. My plug popped out while driving and trashed it. I bought a new harness, and I thought I had wired it the same way: blue, brown, green, red, yellow, black and then white. I have a Bluetooth brake controller. 

Any assistance would be greatly appreciated.

Does the 'new' 7-pin cable have a wiring diagram WITH wire colors and signal name? (not all cables use the same color code)
If not, use an ohmmeter to trace the Connector positions to the wire colors.

Confirm you installed the 'new' cable based on Signal Name Location.

Several resources on web & in this forum.

@michaelroyy, your wiring looks identical to my 2019 junction box wiring, except that mine has a blue wire connected between the trailer emergency breakaway switch and terminal #1 in the junction box.  Yours has two black wires that appear to be joined together with a single terminal lug.  I'm not clear as to what those wires are, unless one is from the trailer brakes, and the other is from the breakaway switch.

The other connection that I cannot clearly see is the black wire exiting the wire loom on the left, which appears to be connected to terminal #6 (but, potentially, to #7) - - I have a red wire connected between the breakaway switch and terminal #6, so maybe yours is just black rather than red??  (I agree with the comment by @MuttonChops re confirming the color codes, because that may what the issue is).  
Maybe double-check each of the connections I have referenced.

Terminal #2 (brown wire) is for the right turn/stop lights - - it appears to be wired correctly.

Double-check your ground wire connections as well.  Often times, that is the simple solution.

If it is of any assistance, I have included a closeup of the drawing posted by @MuttonChops so you can see the wire colors clearly, as well as a photo my junction box connections.  Good luck!!

Thank you both for responding and the details. I will probably be at it today. Probably start out with my meter and work from there on the diagram & pictures. To be continued...

I'm late to the party but this might help : https://johnsontrailerparts.com/how-to-wire-a-7-way-trailer-plug-trailer/ it shows the different wiring colors for SAE and RV.

I think I traced it to a partially faulty rear light. When I checked all the wiring as advised (thank you), I noticed only 1/2 of the lamps were illuminated in the back right. I took off the small plastic housing, but when I pulled the light box off, it looks like the wires go into the big bumper area that looks like it covers the whole back end. Two questions: 1) do I have to take off the whole back-end plastic or am cutting and splicing? 2) where can I get a replacement for the rear light? See pictures that hopefully help. One is of the light, the 2nd are the wires going from the light into the junction box, and the last are wires from the junction box into the 2nd layer of plastic.

I resolved this with Grumpy, Bayless, and MuttonChops' help. I did wire everything correctly after triple checking. The problem was that the right taillight still had some lights, but there were several not illuminating. I did not pick this up the first time. In another post, I explained how I changed out the taillight and everything is working, until it doesn't. Thanks again.
