If it is box tubed i would just re-wire it entirely.
Trailer wiring
I have a 5 pin coming off of my Nitro trailer but would like to go to a 4 pin (my dog has chewed it and I need to replace it anyways). I have a blue, yellow, green, 2 browns, and 3 white. Do I have to re-wire the entire trailer or can I splice two of the above to each other to make it 4?
Thanks,
Ryan

3 White??? Hopefully just 1I have a 5 pin coming off of my Nitro trailer but would like to go to a 4 pin (my dog has chewed it and I need to replace it anyways). I have a blue, yellow, green, 2 browns, and 3 white. Do I have to re-wire the entire trailer or can I splice two of the above to each other to make it 4?

Yellow = left brighter bulb (stop & turn signal lamp)
Green = right brighter bulb (stop & turn signal lamp)
Brown = running & marker lamps (2 wires - one down each frame rail)
White = ground wire to trailer frame
Blue = most likely to brake solenoid
With the 5 pin, you most likely have a "brake solenoid" on your trailer which should get voltage (blue wire) when the vehicle is put into reverse (typically connected on back up light circuit). This should energize the brake solenoid which bypasses fluid pressure from the master cylinder to the trailer brakes so you can back up the trailer without causing the surge brakes to set.
The 2 brown are already paired or spliced and go to the same pin in the plug.
You could go to the 4 pin, but then you'll have to eliminate the trailer brake solenoid connection. In the event the surge brakes set when backing up, there is a manual over-ride on the trailer that will allow you to back up. The problem is if you're needing to use the manual over-ride, you have to get out of the vehicle to set it. If you're in a traffic situation, having to get out to do this not only sucks, but can also be unsafe.
If your trailer brakes don't work and you never plan on them working then a 4 pin connector may be an option.
Just get a new 5 pin connector and splice it in.
+1 my thoughts exactly.3 White??? Hopefully just 1

PM sent, let me know if you have any questions!
Yes there are 3 white coming off the trailer and splicing together to go into the female plug.3 White??? Hopefully just 1

I think Ill just get another 5 pin and just keep it the same.
