Just logged on to Shopkey5 and looked up starter replacement procedure. It says to remove the air cleaner housing to access the starter wiring. This would be the upper and lower halves. I also looked at the wiring diagram. According to it, you should have 2 smaller wires-A black with yellow stripe that goes to the instrument cluster module and a solid black which would be your start signal wire from the immobilizer module. The solid black wire would be the one you would want to jump. You could access the immobilizer module under the dash. Disconnect the wiring from it and pin 1 should be the solid black wire to the starter. I went and looked under the hood of mine and they do have the starter tucked nicely under the intake. It still may be difficult to see the wiring with the air cleaner removed. If you cannot determine which wire to connect to, don't do it. It is much cheaper to pay someone to check it before than after something is fried.
