MAS relay W126
 

This thread mentions a MAS relay. In fact, its pictured. My car has an open spot there and I always wondered what could go there. Now I know.

But I am confused. The 5.6 may be different than the 300 the thread is about. It says: "It seems You did not follow MB doc's explanation above , instead of a separate fuel pump relay and a separate KLima relay , the 1990 model has combined them together as a single MAS relay. which functions as a fuel pump relay + AC relay."

My 91 has a KILMA relay and there is no MAS relay. Just curious I guess.

Ah, I see its a V6 thing.

V6 eh? ;)

The 300SE is an I6 configuration.

The M116/117 engined W126 chassis did not get a MAS relay.
