Unfortunately, I don't remember off hand which pin you apply the voltage to (and I'm out of town right now so I can't go look), but I'm pretty sure you can just try both pins until it works since one pin is the input and the other pin is supposed to be 12v anyway.
If putting 12v to the jumper results in an over voltage error, you can try turning the lights on or running the a/c fans. And if that's still not enough, you can add a resistor to the line, which it what I did with that pot so I could adjust it until it works.
Or you can just get an 03 ecu that doesn't put out the incorrect voltage to the jumper to begin with.
