DOES ANYONE KNOW WHAT THE CORRECT BACK UP LIGHT SWITCH PART NUMBER IS ?THE LATER NUMBER IS 420 AND I THINK THE ORIGINAL NUMBER IS 413 . THE NUMBER IS STAMPED IN THE SWITCH . THE ASSEMBLY MANUAL SHOWS IT IS A 413 ,BUT IT MIGHT NOT BE CORRECT . 307 IS ALSO ONE OF THE FIRST PART NUMBERS . CAN ANYONE HELP ME ON THIS MATTER ??? THANKS JOHN
