Electric Trailer Brake controller harness plug-in

As mentioned in one of the other post the harness under the dash can be tricky to locate. The harness in the vehicle has an empty white connector plug that protects the harness but at first glance it appears the trailer harness will not plug in because of the connector. My customer had been to an independent shop and they had wrapped blue masking tape around the plug to identify it but had not removed the cap. I tried plugging in as did one of our techs but to no avail because the cap was still in place. We had one of our installers look at it and found the cap and plugged in the harness and everything was ready to go. Just one of those Nissan things.
 
Here are some photos of my Tekonsha brake controller install in a 2014 Pathfinder. Like some of the other in this forum, I put it on the left, on top of the fuse box.

I removed the fuse box cover and made a little custom plate to fit it in. The cable was a real pain to reach - it was taped back under some foam way up to the left of the steering column. I could barely get it out (no leverage) and it did have a "cover" on it. I also put in a spacer washer to position the controller properly (right angles to the centreline).

No issues with it so far.

Australian model pathfinder brake controller wiring harness plug

Can any please confirm if this is the right connector?
It was taped onto another cable up under the steering column. I found it by following the instructions on the forum. The Australian model 2014 pathfinder doesn't appear to have the protective cover on it but there is a small blue pen mark on it instead.

Waiting on the delivery of the tekshonka wiring harness for the nissan at the moment.


Hopefully I have attached the pic.
Thanks

Kind of looks like the connector in picture # 3 in post # 1 of this thread, so I'd say yes.
 
It was indeed the right plug and it DID have a cover on it. Actually I suspect it could even be the opposite connector and you could possibly just fit the wires into it, with pins?

Anyway,much easier just to pick up the cable from Tekonsha. Mine arrived yesterday and it fits perfectly. One problem though, when it plugs in the brake controller powers up but with only two dots on the LED screen. Not the "nc" ( not connected) or the "c" (connected) when the trailer is attached or not

The only thing I can think of is that the trailer plug hasn't been fitted correctly and Nissan have bypassed the pre-installed wiring harness in the vehicle when the tow bar was installed.

Anyone else had this problem?

Thanks

Make sure you have all the right relays and connections installed. Did yours come with a hitch from the dealer? If so, you are fine. Mine did not so I had to install a bunch of wire harnesses and relays.

Mine was actually installed by the dealer.
That's why I'm thinking maybe they didn't connect the brake control wire at the rear.
Thanks anyway, I will pull the connector apart tomorrow and have a look.
 
How did this work for you?
I have installed a prodigy with a brake harness from the US, I am getting the two dots and the n.c, the controller manual lever operates the brake lights on the vehicle but doesnt connect to the brakes on the van/trailer.
My tow hitch and plug were also was installed by the dealer!?

It sounds like your white (thin) and white (thick) wires are reversed. Just a guess. Check my post #3 . You have to really check the wires carefully due to the non-standard color choice by Nissan.
 
Thank you so much! I spent half an hour trying to figure out the plug. I finally read your post and discovered the "protective cap". I wondered why the harness wouldn't fit! Thanks so much!
 
Sooooo... Am I the only one who went rogue and mounted the Tekonsha here? :blush:

/This was done well over a year ago
/I just found this thread
/I can remove it when not in use
 
I am going to install mine this weekend...I will look at that location as it looks interesting. As long as it doesn't block the 12V outlets as I use those.
 
When it's there is does block the 12 outlet on the driver side. However you probably could fit a slim cig plug in there. This is another reason that I don't leave it installed when I'm not towing.
 
awesome man, picture really help, now i wonder in off season like winter time can i unplug it leave it out or has to remain in pf whole time?

When not in use my controller stays in the cargo hold with the tow hitch.
