I have found mine, but it is not conected. I can not find any socket to plug it into. The wires to the pump is about 30 cm long with a two pole socket on the end just hanging from it.
I think it should be coneckted to the heatvalve over air tank, but that is alredy conected to other wires. It is getting cold up here in north, so i'll aprisiate some help

May be your pump is not okay and therefore someone had disconnected it. You can check the pump by connecting the plug with 12V and ground. If the pump is not working you can take one from mercedes c-class passenger cars. They are easy to find. But as far as I remember you have to lengthen the cables of the c-class pump.
