Does anyone know which is the Fuel pump relay? Also where can I get a new ECM?

Thanks as always for any answers.

I think I saw that thread and wanted to comment that I didn't think a 77 (assuming k-jet) would have an ECU. But I decided to keep my mouth shut because I don't know w116.

In my 73 and 78 107s, the fuel pump relay is above the fuse panel. I have to take the cardboard sheet surrounding the fuse panel off to see it. It was a metal ice-cube shaped relay, one of many there. You could swap them out in my cars too because they are all the same. I don't know if the w116 is similar, but I would guess so.

(In late 78 on the 107s, they switched to a different larger relay.)
