I am installing a Hopkins breakaway into my Toy Hauler and need some help with the wiring
I have run an extra "Blue Wire" along with the main wiring harness running from the plug back to my junction box
Can someone let me know if mu wiring diagram is correct or have a made a blue :) I have the Hopkins wiring diagram & tried to adapt it to what I have just not sure if I have it right or not
Thanks, I already have the wiring diagram I was hoping that someone could take a look at my draying to ensure I have it correct before I start with the connections

Your drawing appears to show a connection of the trailer brake wire to the brake light circuit. If so this is incorrect, the two circuits must be independent of each other.

Alan is correct.
It seems to me that the blue wire that you show going via the switch (I assume that to be the brake free switch) to the trailer plug, should be going to the trailer brake operating wire at the junction box but it can be picked up at the trailer plug as you seem to have done.
The idea is that when the tug & trailer become separated, then the plug pulls out operating the switch & battery from the unit goes via the switch to the trailer brakes.
edit ... If the terminal that you have used at the trailer plug is indeed the (blue) brake operating wire then you are correct. The standard colour for the van brake operating wire is blue, so you are probably right.
See attached plug wiring doc.
Just pull the brake free plug out & see if the brakes work. Or I assume that there is a test button on the unit that you can use.

Just realised where I may have been a little confusing with my drawing, in the junction box the red line I had through the middle was not a wire it was just a centre line for my drawing, I have now edited the drawing and hope that its much more clearer
think I may need to head off the an Auto Electrician on Monday with my drawing in the hope that he may be able to give me some advice as I need to get this finished so I can move on with other parts of the build
New picture is attached if anyone has some advice its much appreciated

I have no first-hand experience with a Hopkins unit but there is plenty of info available by just googling Hopkins breakaway.
I think that this diagram may help ..
