bULK HEAD

HI!I,M BUYING A 66 DART,THE PO TELLS ME HE Has to start the car by jumpING THE SOLENOID AND SAID IT,S THE"BULK HEAD" IS THIS PART THE BALLIST RESISTOR??OR ORANGE BOX?THANKS FOR ANY HELP.

Need to know it the problem is "no crank/no start", or "does crank/no start".
If it does not crank, it could be the starter relay, the neutral safety switch, ign switch, or the wireing between these components, including the bulkhead connector.
