Johnson Controls Ignition control

trying to replace a JC G776-RGD-11 with the Honeywell repl #30W33, instructions have a blue or yellow going to MV/PV slot and a yellow going to 24V slot, I have 2 yellow wires --how do I tell them apart?

    Your post

    Not a bad idea to get a pro in there to actually see what's happening.  The blinking light may be normal operation, but with not knowing and or looking up your control I could not even point you in the right direction.
