This is a Corrado, which is identical to the mk2 under the bonnet. You can see the wiring loom running over the top of the bay and round to the battery on the right of the pic.
The headlight and sensors for the left of the bay run straight to that side, and all the rest of the engine loom, ancillaries, power cables, lighting, etc runs down the right.
