replacing turn signal assembly

I am trying to replace the right front turn signal assembly on my 1998 BMW 740I and before I get started I was hoping for a bit of guidance to avoid unnecessary work. My question is, where do I take off the damaged assembly, is it under the fender well or do I come under the air filter area? Or neither?

Thank you in advance

I thought I seen somewhere online where it tells you how to do that. You may have to do some searches.

I posted the steps with illustrations on the 98 740iL lights removal. Check it out there. Let me knwo if you have a problem it is easy...
