i have a 73 620. the head light and tail lights work but not at the same time. the pull switch is faulty i assume. one pull i get head lights no dash light light or tail lights or running lights. 3 clicks out i get dash and tail to come on but no head lights. brake lights and reverse light work fine. i bought a universal pull switch but it has 5 wire hookup to screws. the stock is not like that. someone please help. i got a fix it ticket and its bout due. joined this site to hopefully get some help from fellow datsun owners
