OK. I just noticed you have an 08 sedan. On that 4A-5 is yellow instead of green.

I have an 08 Sedan fuse box on my test bench, and I also see the missing wire in 4A-20 (which the EWD for an 08 sedan says should be there). Those two wires are actually tied together as a single input into the ECM, so you probably only need the yellow and that is probably the reason for the lacking blue.
