'93 complete tail light conversion problems

[Jcooper0531200p]

I got a wild hair about a month ago to put a flat bed on my ranger, its since been abandoned because of the price of lumber, but I did decide to go with the tail light setup I had in my head. My problem is with the marker lights I'm trying to use for brake and running lights. I'm getting power to my brake lights even when the brake isnt pressed, my 3rd brake light isnt working though. I'm not real good with this scope of work but figured it wouldnt be this difficult to manage. Any help would be appreciated.

do you have a ground?

do you have a ground?

I havent really thought much of it. If I'm looking at the harness correctly all of the rear lights share the same ground. My blinkers work perfectly fine after I swapped to a LED flasher. All of my lights were working before I decided to get rid of the stock lights. I've put resistors on the brake lights but nothing is different. I've been using the wiring diagram from the haynes manual and it shows green and brown going to a single light on the factory lighting setup as well as the ground. One wire is supposed to be for running lights and the other for brakes. I wanted to split that and run 2 separate lights. Not sure what I'm missing

I've checked and have a solid ground. Not really sure what's going on here.

You will have split the grn/bundy wires to separate LEDs. Same with the other side.

Currently I have the green going to one light, brown to another. When I turn my running lights on they flash once and go off. Brake lights do not work at all. Fuses are good.

I would disconnect the rear lamp harness and test the vehicle side of that connector for proper operation.

When I did my LED lights in the rear just oval truck lights. I had to wire resistors in, The LEDs don't have enough resistance to make the turn signal switch work right. I had the same problem, lights would stay barely on, and would kill my battery. Problem fixed with resistors.

These are what I ordered.

I believe they make blinker relays that do that as well but I've only casually looked into the conversion and have not heavily looked in to it.

I tired that, i put LED blinker relays in it before i did the resistors. Didn't work. as soon as I did the resistors everything started working right and have had no more issues.
