2002 Ford Galaxy electrics

Hi im having trouble with my side lights all wasnt working.ive changed the mini blade fuses 5 amp yellow/brown in poision 56/57 now nearside works . Off side blows the fuse .so I went through the car starting from the back cluster all bulbs are fine followed the wires ( what I chould see ) to the fuse box under the stearing wheel no look there.tryed the front same. No problems that I can see.so I ran a wire from leth hand cluster into the other cluster. That now works.so I have 3 lights working.running off the left hand side .as for the front I cant get to work because the side lights on the front are 2 black wires.so I ran 2 wires from the leth to the right front and it blows all 4 cornors ( just the fuses ) is there and other way of solving this or can I run a wire separate from the front right to the main light switch in the car
