1989 300 SEL, Does it have a ECM / ECU?

[outofspec]

I’m striping a junk 1989 300 SEL for parts for my 1989 300 SEL. I thought I have an ECM / ECU (Engine control module) on this car, but I can’t seem to locate it. Among other parts I have the ABS module from the fire wall, and the ignition control module from the drivers fender, but I thought I had a ECM like the later model 103 engines. Does anybody know if I do and where it is located? I don't want to send it to the crusher without completeing the harvest.
Thanks and Happy New Year!
