URGENTLY NEED HELP!

Hi there guys need some help!
I've got a black eurovox max V that for a while does not power on. After doing much research I discovered that to bring it back to life I can try 'j-tagging it’. I bought a eurovox JTag from tailor made circuits and it arrived today. Although this may sound really stupid I’ve been looking about on the various forums and I seem to understand the process behind performing the actual operation but I’m stuck on how to connect the JTag to my eurovox and my pc! I know you need a parallel port and I do have that on my pc but how do you connect the JTag to the box? Do you need to take the casing of the eurovox? Yes I know I must sound really dumb and I do apologise for my ignorance on this matter but I’m not very technical at all. I'd really appreciate it if someone could give me a step by step guide on actually how to CONNECT the JTag.
Cheers dudes....and I hope someone can help and save me from insanity! LOL
