I have a 91 S10 Blazer. I am trying to install an alarm with remote unlock and lock. I don't know if I have a positive unlock/lock or negative unlock/lock. Does anyone know? Or how can I test? I also can't find where to hook up the parking lights. My alarm sends a negative output. Any help is greatly appreciated. Thanks

Do these 2 wires need a positive signal or negative signal to activate the locks. Once again thanks a lot
