i think that relay has a resister attached to it (well, the one out of helmann's did).
i think the ECU can direct the relay to feed power thru the resistor or straight thru - either way, it's power source should be the circuit opening relay so the ECU can drive thing properely? Someone who did elec engineering can explain why the resitor's needed or what it does?
check that it's wired up something like the diagram on page1 of this PDF:

FWIW: the toytota part numbers are:
Relay 28380-43010
Resistor: 23080-70010 (0.71 ohms)
