Hi Rick - I'll try and communicate this way as it might help others with a similar question about your product.
I have a European specification W201 => a 201.018 chassis - year 1992 with an eight pin connector.
I watched your video but was wondering how us children of a lesser god with 8 pin connectors have to sort out the power from plug 16 which doesn't exist on the 8 pin socket version - I assume you just crocodile clip straight from the battery. Is that right?
Does your documentation include the 201.018 chassis?
