WAS THAT "17" IN THE DIAGRAM FROM rivermikerat?

GLAD YOU GOT IT FIGURED OUT, NOTHING LIKE NOT KNOWING WHAT YOU COULDA MESSED UP...AND IT WIND UP BE NOTHING AT ALL!

EVEN WORSE IS REPLACING YOUR BAD JEEP IGNITION MODULE WITH A NEW "BAD" MODULE, THEN RIPPING DEEP INTO THE WIRING FOR TWO DAYS, BEFORE YOU TAKE THE NEW ONE BACK FOR TESTING TOO!.....I NOW TEST NEW STUFF BEFORE I LEAVE THE STORE
