Discovery 1 1996 300tdi, I am trying to connect the wiring from the 1533 timer to the thermotop v 8pin plug but cannot find any diagram for it, please help. I know the wires are red 12v-black ground-orange wbus to heater-blue 12v timer out. So do not know which holes to put the wires in and (should there be wires for the fuel pump as well?)
