Stupid boat trailer wiring question

Ground is the trailer. But if you want to save yourself a a future headache, run a ground to each light and use non trailer wiring kit wire now.

The wire in the kits and proper grounding are about 95% of brake light issues.

The ground wire coming from the lights- attach that to one of the wires that is connected to the pigtail? Any tips to help make a good ground connection to the trailer?

Get 2 long arse pieces of wire

On the trailer side of the plug, connect both of them to the white ground wire

Run one to each light for a dedicated ground

This way you are not relying on the trailer metal to complete the ground from front to back.

*There might be a better way to do this but this has worked best for me on my jon boat trailer.

best thing to do is go get a 50ft 16 gage extension cord (only costs $7 at home depot), cut the ends off then cut it in half and use that as your new trailer wires.

it stays flexible and is well protected, its a heavier gage wire then the crappy trailer wire kits give you, and it will last you a lifetime and be trouble free.

each side gets:

green to ground (mounting lugs for light)
white to light (running light)
black to blinker (turn signal)

also put a big blop of silicone all around where the wires to into the light fixture. because its not sealed there no matter what the box says and water gets in if you don't seal it yourself.

at the truck plug make these connections:

brown is the running light so it gets soldered to both white extension cord wires

the white from the truck is the ground from the truck so it gets soldered to both green extension cord wires

the yellow and the green are the blinker wires so now plug the plug into the truck connection and turn on a blinker to test to see which one is the correct black wire to connect to for that blinker and then you know the black goes to the other one.

now just wrap everything real good with electrical tap and use wire ties as needed so nothing hangs loose and it will last you 50 years and never need to change or replace your wires again (well maybe the truck plug in maybe)

after years and years of needing to replace trailer wires every few years I finally figured this out and it is the perfect solution and it solves the biggest problem with trailer wiring in that they try to use the trailer as a ground connection. my way eliminates that bad ground connection caused by rust and all sorts of other things like tilt connections

Damn thats pretty solid I will have to look into that

it also gives you enough wire (roughly 24ft on each wire) to go up high without having a break in the wires anywhere if your lights are on top of posts to keep them out of the water.

for bigger boats just buy the 100ft extension cord
