I bought a new 6'x12' utility trailer in 2016. I was without it for a few years, but sole owner and no one hacking with it, and mice ate through the wiring and I just got it back.

I replaced those mice eaten pieces, but when hooked up to my truck the signalling is not correct. When I left signal, nothing lights on the trailer. When I signal right, both sides light flash.

There are four wires, and a fifth white ground wire.

So I cut the pieces of mouse chewed wire out and replaced... white wire goes to white cut wire... green wire goes to cut green wire. I didn't "cross contaminate" wires. Cut out the eaten pieces, put on a new extension... the end. This doesn't seem like rocket science but it has me miffed.

I've had over 200 pinball machines and have brought games back from the dead. I'm not boasting, but just point being this isn't my first wiring job.

White ground wire is making good contact. The 'source', the truck, has been connected to a different trailer and its fine. Its all in the trailer wiring.

Any ideas?

Thanks

I appreciate the help. It's going to be something ridiculous I'm sure

I got it all fixed. The wiring replacement I did turned out to be fine... The right break/turn signal housing was compromised make things not run right. Once corrected, all is finally good. Thanks for all the input
