do you have any more pics dude, like from the top over the dizzy to see the black lead?
there should only be a green one coming from the dizzy..
also does any of the coil rest on the body work it looks very close :|
do you have two barrels on your dizzy?
also have you had it running yet??
it'd also be worth checking behind the glove back at the fuse box to make sure no wires have fallen off.... i got my van with a melted loom and turned out a wire had fallen of the fuse box and shorting out....
if your connecting your battery + then - and the terminal sparks when you connect the - then you have an open circuit... do you have a working interior light when a doors open? or anything turned on when you connect up? not really a worry but if, when the vans fully working you get flat batteries often this will be the problem...
either way check check an check everything again, before you connect the battery an take it for a spin just to make sure its all ok an everything were its suppose to
online somewhere, maybe the samba ones you've already seen i cant remember, but theres a coloured diagram that may be of more use
