so i went and looked at a 94 ford mustang 5.0 ho 5 speed. i can get it for 900 it only has 65000 on it. the cars in great shape. the only problem is that when the battery is hooked up the alarm goes off and you cant start the car. i know its the factory alarm, the stickers and in both windows. i forget the name its like a 4 letter word. if i unplug the harness from the truck will it fix my problem, and where is the plug located in the trunk thanks
