Installed LEDs now no flashers 2004 Argosy

So I swapped every bulb out to an LED on the truck and installed these turn signals. Now the flashers don't work. They light up once and just stay on. No blinking so no hyperpflash just solid on constantly. So after researching the forums I installed a new style electronic LED compatible flasher relay as everyone suggested. Did not fix the issue at all. They still just stay on solid no blinking. Do I need one of those load resistor things? I read those only solve the hyper flash issue which I don't have. Trying to avoid tapping into an old electrical system if I can. Any advice
