Viper car alarms are hardwired into the electrical system of the vehicle. The electrical harness is color-coded to wire into specific parts of the electrical system. The way the harness is designed makes it simple to find the parts of the system you need. Removing the fuse in a Viper alarm is a standard part of installation, and replacing it is a simple task that almost anyone can do.

Step 1

Pop the hood of the car and locate the red wire on the primary wiring harness, also known as the H1/2 wire. Find the positive terminal on your car's battery and follow the small red wire until you locate the fuse holder box on the wiring harness. Be sure to follow the small red wire. The large red wire connects the car's battery to the car. If neither of these fuses are blown, examine the fuses in the car's fusebox.

Step 2

Open the fuse holder on the wiring harness and pull the fuse with the fuse removal tool.

Step 3

Take the fuse to the auto parts store and find a replacement of the same type with equivalent voltage.

Step 4

Pop the new fuse into the fuse box.
