what is the actual issue? Are you not able to get the blue to flash?

even before the blue light not flashing i am only getting 4 sets of blinking yellow instead of 5 sets per step 4 and then has a solid red and yellow on at the same time and thats it. according to step 5 there should only be a solid yellow before turning key on.

Do the first 4 steps of programming with only the black connector (power and ground). See if it blinks properly then. If it does, there is a problem with ignition wire on the 20-pin.


If it still fails, RESET the EVO, then reflash it.
