I know this has been asked a few times and i've used the search facility, but not had much joy with it. I haven't got a Haynes manual either

My coil wiring was butchered by the previous owner and i'm trying to sort it out. One of the connections was bodged onto the terminal and it split (the terminal). I've managed to get my hands on a 12v coil, is this the right one? If not, can I use the terminal?
I'm also unsure which of the four wires goes where.
Any help would be greatly appreciated!
