Accessory rear lighting help needed

Picked up a couple of 3" led running an stop lights to add on my 2013 Polaris Rzr 800 S. I was expecting to include a relay with the purchase to tie into the wiring but was told that I would’nt need it and that the shop installs these lights without one all the time.
Thinking then this will be easy, I proceeded by first testing the new tail lights wiring compatibility.
After much time testing the new lights I found they don’t work properly.
I can get the running lights to function but not the brake portion of the lights. It seems the terminal(orange wire), goes dead on braking. I think this is where the relay comes in to play.
Any solutions would help.
