The engine here is depicted in preparation for hoisting into place. The exhaust ports are covered to prevent ingress of material, there are minimum of wires and pipes since the ones from the other engine would be used.
There is also a makeshift lifting system which I found and copied from page 151 of 'Luftwaffe Fighter Bombers and Destroyers 1941-1945' As you can see they fitted temporary legs which I made from aluminium to keep the engine bottom off the ground and prevent damage to the piping. There are also c Channel sections (also scratchbuilt complete with lifting hooks) bolted in place instead of the engine bearers. These had hooks from which the engine would be raised in place. The channels are welded onto plates which fitted exactly in place of the engine mounts. Back to the 02 now.
