I swore it was in the archives but I could not find it either (& I have seen it there ). iirc on the bulkhead the 2 main in/out wires, the one "in" from the fusible link and the "out" wire to the alt you just run another one (two actually)wires (in effect)around the bulkhead to get by the problem of the great amt of current going thru the inadequate bulkhead connectors at those 2 points. If you have 2 unused connectors in the bulkhead just drill them out & run 2 wires thru there for the 2 parallel circuits. If not then drill 2 small holes in the firewall. www.madelectrical.com will have addt'l info for you. If I think of anything else I will holler.
