I did a search of the last year looking for the awnser but didnt find what I am looking for

I have fitted morrets to my car and when Wiring up I have 4 wires, the earth and + are pretty obvious but what isnt that obvious is the two blue wires.

I'm guessing on of these is for the full beam, but which wire is which? I have a lightish blue wire and a darkerblue wire with a scotch clip on it.

What does the fourth wire do? as you probably guessed I dont have any fitting instructions or manual and the morette site isnt working
Ta in advance.
