Kaehler wiper relay

Since last November, the wipers will only work on the fastest speed. I replaced the wiper relay, which looked like the one highlighted in the second picture: wide, flat metallic case; seven pins. I replaced it because I heard a clicking coming from it each time I turned on the intermittent wipers. I got it from the dealer because I could not find it online. This did not fix the problem, nor did replacing the fuse for the wipers.

When I looked for a wiper relay online, every parts store suggests the one in the first picture: a tall, skinny plastic relay manufactured by KAE. I cannot find where such a relay would go on my car (1978 240D). Does the KAE relay fit the 1978 240D? Where does it install? Thanks in advance for any help.
