Alpina Momo 4 Spoke - horn wiring

Post by Rick Eickhoff » Fri Oct 30, 2020 4:48 pm

Finally received my Aplina Momo -4 Spoke steering wheel - from Europe. Took forever.

This steering wheel has two horn buttons - one on each of the upper spokes.

I’m using the Momo 2006 adapter- which lines up and fits correctly.

My question is how should the wires from the two horn buttons (Red wire) and (Green/Yellow wire) be wired into the Momo hub (black wire)?

Have you had it re-covered or is it new?

The horn button grounds when depressed, energizing the horn relay. I assume the two wires go to their respective buttons, so would connect to the chassis side wire.

My '84 ETM shows 4 switches in parallel all grounding.

Got the horn wiring figured out. Thinking about using a Momo accrentric hub spacer. The 380mm wheel is blocking the upper portion of the gauge cluster. Has anyone used one ?
