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

Not what you asked for, but maybe this will help. Resolder the largest of the pins on the board. Those seem to be the ones that are causing problems for people.
