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 +
