this product help keep all things in order and I have not had any issues with wiring
I can't say enough good things about the staff at etrailer. They helped me pick out the correct items to install disc brakes on my boat trailer and the technical staff was extremely helpful in helping me better understand how to perform the installation. This was the first time I ever install a new brake system and their help enabled me to easily and successfully complete the installation. A+ for the product quality and for etrailer staff!
Would not recommend this package at all. The main cable (vehicle 7 prong cable) had all the wires miss attached, IE the brown was not the running light but the constant, yellow was constant etc, the only wire hooked up correctly was the white ground.
So during installation I assumed the harness would be correct, hooked up to my truck and not have a massive short in my truck due to the improper back feeding and drain. I had to bring another vehicle up and trace every wire individually with a test light to wire the trailer correctly. Good news, after 5 hours I was able to rewire my trailer, bad news I no longer have a truck to tow it with due to the short. I can not even begin to imagine the undertaking of now having to find the short in my truck.
Would recommend against purchasing this product at all costs, you're better off building one on your own harness which I guess I should have done!
The location and color of the wires in the plug is completely misconstrued from industry standards! Green where it should be brown, red where it should be yellow, brown where it should be green, yellow where it should be purple. This makes the wiring a real trick!

Yes, you will need to check the studs in the junction box, they are labeled by function. Hopkins does not follow the standard colors for functions. I know that's frustrating but it's always a good idea to test your wiring with a circuit tester by function to make sure you are hooking up the correct wires to the correct stud.
Watch how you wire this up but once I started following the directions it worked perfectly. Would have liked a better waterproof box for wires but seems to holding up to the water.
Everything I have purchased from you had been the highest of quality. Very quick delivery. I rebuilt my boat trailer with your part and I couldn't be happier
The color coding on the wiring block does not match the wires in the pigtail …. Be sure to test when plugged into your vehicle
GREAT PRODUCT
