Installation Extension fog lamps Opel Omega B Year of manufacture 1994

Hello community! I am now building on a model similar to my Opel Omega, it is a vehicle in which the following lamps do not work: – the front right fog lamp – the rear fog lamp(s) In addition a question: Was the rear fog lamp in the year 1994 already on both sides? Or was there only one rear fog lamp? Can anyone possibly tell me how to install the front fog lamp(s) out and again? I really don’t have an Ahnun g, how to get there and how to change the lights.http://img708.imageshack.us/img708/9234/foglight.jpg I am really grateful for every hint, not for nothing I ask such hobbyist questions here in the forum!
