Trailer turn/brake light setup

So, I have a 97 Tacoma and recently got a small utility trailer. I discovered the flat four pin trailer connector wasn't hooked up and am trying to figure out how to connect it. I have turn signals and running lights working with trailer, but no brake lights, wondering if I missed something.

 

How did you hook them up these trucks have independent turn brake lights. The flat 4 trailer connector is combined turn brake. You need one of these adapters to make it work https://www.etrailer.com/Custom-Fit-Vehicle-Wiring/Hopkins/HM43315.html

 

Ok, will have to look into, had tried to avoid because I've seen lots of folks having problems with an adapter, is this one better/corrected?

 

I've had 3 of them across 3 trucks and have never had a problem. I have never heard of them having problems.

 

I've used that exact one and had it fail in about 3 years. The components inside the converter usually short out and start doing weird things with the running lights and brake lights.

The last time I replaced it I went with this one since it has it's own power wire that you connect to the battery. https://amzn.to/3NOu2Wc
This seems to have solve the problem of it failing, but only time will tell.
