I could be wrong here - but 9 and 7 are never connected to each other.
Looks like on the load side of the fuse, 9 is only connected with 6.
7 and 2 are on the load side of the other fuse.
6 and 9 are connected to one relay, and 7 and 2 the other.
1 appears to be power that feeds both pairs of loads.
