LOL -- they actually soldered the 1st and 2nd starter wires? (a.k.a "jumping" two wires)
Technically this is incorrect to do, after extensive discussions about Nissan and other vehicle makes 1st and 2nd starter wires, many decided that these two circuits must be electrically isolated. I would un-do what they did and use an SPDT relay to relay power to the second starter wire via a positive trigger from the 1st starter wire. Here's the diagram I would use:
