93 nissan maxima door locks

Heya, I'm currently putting in a Crimestopper CS-2015FM alarm/remote start on my 93 Maxima, and here's my dilemma: I'm trying to wire the door locks for driver's door unlock priority and am having the hardest time finding the driver's door motor wire. I'm fairly certain that I've found it (two 14/16ga brown wires that are neg. at rest, but 12v when I hit unlock), but I'm curious if I can use only one of these wires with my relay or is it necessary to use both wires? The installation instructions aren't really clear on this, and I wanted to get some clarification from anyone that's familiar with this configuration. Thoughts anyone???

Thanks for the reply, but my question is since I found two brown wires, which do I need to use? Keep in mind, both wires test the same...
