Hi,com4t4u:)
what I use and most people I come into contact with use is Auto Cad. I know that if you have a fast conection you can download a pirate copy from the internet.
Personally I had to take a 30 week evening class once a week to be able to use it. To do drawing you would need to make up or download a symbol library the ones you can download are never as good as the ones you make yourself.
I would recomend enroling in a evening class to learn CAD you will never look back.

There is a freeware program that you can get from the net. Its called TINYCAD. Its only 198kb. I can email it to you if you send me your email address. I tried to attach it to this message but it says the file is too large.

There are dedicated programs for producing wiring diagrams, I looked at one from Reading University some years back - but at +/- 3500 GBP decided against it.

A pencil and paper prior to Tinycad work fine :D

Oracad is a program used for electronic wiring diagrams. I have a copy but don't remember where I bought it.
