grill instalation ?

i have a gunkol ELE 0499 grill element which has a total of 4 conections.1) double connection joined to make one.
2) small conection conect to plate.
3)single conection
4)singal conection
As you look into oven this will be 1-4 right to left.

An election took this grill out for me but never came back to me !

which wires at back go to which connection i am not sure what colour wires there are. I will have to take the oven out again. So what should i do.
