Question
1999 Mercury mini van villager
code scanner said bad knock sensor
had to pull plenum off to get to it and the new knock sensor reads the same as the old one,now im down to a wiring harness that goes to the ECM, where do i find a wiring diagram on the Internet? please help me tnx

Answer
Jaymes,
  AlData and Mitchell on Demand offer such diagrams but you have to "join the club" to gain access to them. O'Reilly Auto Parts sells "credit cards" that give you access to "on line repair" for 1 vehicle for various periods of time, depending on how much you pay for the card. I think they offer 3 month membership, 6 month membership and 1 year memberships.
  Why does it have to be off the Internet? Any Public Library I have ever been in has a "Reference Section". In that section, they have automotive books that may the information you need. You can't check out the books but you can photocopy any pages you need and take them home to trace the wires.
  In closing, please note in my bio, I'm a Parts Specialist, not a tech but I hope this helps you. Good luck.
