Very nice tutorial - thanks!
Erik, the drain plug for the blinker fluid is located 3" below the hutwrak. You'll need a 13/32 wire pick wrench to remove it.
Priscilla, you have probably fixed this by now and I don't know the answer to your question, but - I would look at your present cord and try to "gestimate" the diameter. Then, I would pull the cord out as far it is goes - again gestimate the length.
I'm guessing that if the cord you buy is too long - you can cut it so it is just a little longer than your current cord (that way you can shorten it later - if needed).
