Blinkers not working after LED light install

I'm sure there is a thread on here about this. I couldn't find one. I installed full LED rear light fixtures in my gf's 2007 TRD Sport. Everything works but the blinkers. Running lights, brake lights. No flashers up front or rear or light on the dash. I heard you need to install resisters to trick the computer since LED puts out much less power. But i installed the stock lights back before anything else and the blinkers still don't work. The flasher module/relay was also replaced.

I did check the horn/cruise fuze...the kit said it might blow that. PLEASE HELP!!
