Just got a 95 C280 running purchased hoping for wire harness problem, but just finished a head job w/ 2 burned valves. Car running excellant, but the stereo appears to be missing a couple of components. The box in trunk drivers side that appears to be an amp is there, but a multi pin connector w/ two thumb screws just forward of it is missing its component. Any ideas what was there. The CD changer is also missing if that is what plugged into the connector just before the battery. I seem to have no continuous connection to the speakers from the front console connections.
