I had to go to a shop to get the 22 mm nut off my 1977 450 SLC, so I can put a Nardi steering wheel on it.

One hour after taking off the old wheel the adapter arrived, the "new" universal adapter doesn't come with instructions, unlike the old 3320 adapter this one has an additional plate with two contact brass circular strips.

From the bottom of this extra plate are two contact wires. It looks like I need to pull out the two MB contacts.

Has anyone done this using the new 2802 adapter and any tips?
