cheers SI
My suggestion is to find out what the wires go to then figure out the relay.
Look up a diagram for both cars then modify as needed.
The relay pins are
30 Common Contact
85 Coil
86 Coil
87 Norm Open Contact
30 Put power to be switched on this terminal
87 Fuel Pump Hot lead goes here
85 and 86 control the relay closing.
one will go to ground or - and the other to a switched 12v +
