Fuel Pump Relay Schematic?

[tatalina]

Does anyone know if there is a schematic published for the electronic relays? I'm primarily interested in one for the 5500 fuel pump relay w/kickdown, used on the '85 500sel.

I'd like to rebuild my old one & keep it as a spare, but don't know the pin voltages & can't read the values & p/ns of a few of the components.

Thanks
