was ist das für ein Bauteil?

[V.A.K.]

Ich glaub auch dass Gernot Recht hat.
So ähnlich sieht das aus:



Transmission Control Spark Solenoids
Often referred to as T.C.S. Solenoids; these solenoids control vacuum to the distributor vacuum advance unit. The solenoid determines when and how much vacuum to release. Typically a vacuum line from the carburetor enters the solenoid and another vacuum line exits the solenoid to the distributor vacuum advance unit (some applications have multiple inlet and outlet lines). The solenoids also rely on an electrical signal provided by other T.C.S. system switches/senders via an electrical connection on the back or side of the solenoid (the Engine Harness or T.C.S. Harness plugs into this connection).
