Keyless Entry Help!

[Danny Boy]

So I just purchased a keyless entry + Security system from ebay, I'm confused on a few things. I have an 01 alero, I have the appropiate wiring diagram indicating witch colors are what in my vehicle, bulldogsecurity.com shows that the white wire is the unlock and lock for the doors, does this mean I need to splice into the white wire twice for negative and positive (door unlocks??) Any help would be great, I'm sure all have more questions along the way, thank you
