It doesn't matter. The resistor box has a 12 volt main Supply coming in. And if you open it up and look inside, that just branches out to 4 individual resistors. All four of the red wires are the other ends of the resistor which are all connected to the single main power source. After the power runs through the resistors it is no longer 12 volts. It drops down to, eh, ..i think 5 volts.

So in effect it's just like twisting 4 wires to the 1 main wire and inserting resistors in the 4 wires that you twisted to together. But it's just in a box with a plug.haha
Anyways I hope this helps
Glad you got your car back, sucks it had to get stolen in the first place. We had one stolen and recovered too, lost a set of wheels. $500 to the tow guy.
I know how it feels. Good luck
