I just received my alarm and am going to install it myself. I noticed what appears to be an error in the instructions. Figure 3, showing the removal of the rear cowl panel, is the same as Figure 1 on the same page. Is there anywhere to find the correct picture? I already tried the Circle BMW online instructions and they have the same error. From those of you who have already installed yours, is this a difficult step or will I be able to figure it out once I am in there? Also, how is the trim and liner in the trunk held in where it needs to be removed? Do I need a special tool for this?
