Believe it or not it's a 20Amp fuse to the ECU.  Signal goes to the main relay, latches then power is applied to the ECU via the 20amp fuse.

Same relay also supplies power elsewhere as well via other fuses

I'm not 100% sure I understand what you're asking :undecided:

Are you asking what is ECU for? ECU is the Engine Control Unit...the cars brain :wink:

They're not very descriptive of what they are actually for, my model has engine icon pictures rather than ECU text on 11 fuses, couldn't say which one does what :Dunno:
