The first pic in puzzle #2 is the X11 diagnostic port, which is used for diagnosing various engine controls. The second one, part #004 545 5532 is your EZL. The second pic in this post is a combination of the fuel pump relay (FPR)-- it says 6000 rpm kickdown. The one to the right of that is the Klima (air conditioning) relay. To the right of this would be either a red-top or a black-top OVP relay, which has one or two 10A spade fuses in it under a little plastic window.
