I'll second epsonix's suggestion; get a hold of eLearn for the 159, or the nearest equivalent. You'll be surprised at how unamazing it is though, the wiring diagrams are pretty small, hard to zoom and in general nothing like you get in a Haynes manual (why don't why have one??).
I bought the DVD as an iso off an ebay seller, but I doubt he was licensed to do so at the price I paid, so you might be as well to find it on helpful 'sharing' site.
Top tip, once you get the DVD, open it, locate the 'Image' folder, copy it somewhere on your computer.
Open the files in something like irfanview (they're mostly jpgs renamed .image).
For an easier life, you can use bulk renamer or similar to change the file extension to .jpg.
then just scroll through the pictures in their max display size. There are more than 5,000 though.
