Hi,
I’m currently building my second H5(A3) and I was wondering what are these 3 connectors on the motherboard: J2 (close to the external floppy connector), 2 rows of headers below the GLUE and the « IO » connector next to IO port 4.

And one extra questions :Anyone knows the reference of a VGA connector that has the right dimensions to fit on the H5?

The double row headers on the right are for the Falcon RAM board.. most don't use it..
Top middle (as in your pic) is DC jack for power (to power ultrasatan etc) , but ive not got around to trying the connectors I got to for it.
Far right header are spare IO pins - nothing uses them currently.

I don't know any part numbers, kinda assume any will fit.

Don't listen to him @olivier.jan… I think he means left on the pic above, but that it is the right header of the two needed. Could be my translation misunderstanding this.
