If you're asking where the location is in terms of the body, it's driver's side accessible (barely) from the bottom. My lift makes it a little easier to get under, so I don't know if you actually do need ramps or jackstands, but I just get out and crawl right under behind the wheel well. You'll see a drive shaft and follow that to the front until it ends and it should be near that, just above. Just in case you don't know what a starter looks like just google image it and you'll get the idea. My yellow wire is the only one that has any play in it so I found it that way.
Don't know how kosher it is but after having to crawl under a couple times I got under and wiggled and wd-40'd it a bit. Been working steady since then. I plan on doing a permanent fix in the near future, just haven't been able to find time between work and school.
Edit: After googling a bit it seems WD-40 isn't the best to use on electrical connections. Works as a temporary fix but leaves a film that collects dust effectively insulating rather than conducting. I still stand by my WD-40 since I plan on replacing the terminal in the near future, but if you're looking for a long term fix I can't necessarily recommend wd-40.
