If your oven states the 'model' on the front eg. SE86 or whatever, you can locate a user manual on the web and it shows you all the electrical drawings, etc, thats where I found mine for a second-hand oven and found out I had to set the clock etc. Handy to keep it on your PC for reference. I could have a search for you if you state the model number but some sites charge and send you out the booklet. I cant remember the site I found mine on.
