The function of spark plug wires is to link the coil, distributor and spark plugs together. The coil turns twelve volts of incoming electricity into 20,000 to 50,000 volts and sends this jolt through the coil wire, which is connected on the other end to the distributor. Inside the distributor is a rotor that spins, and directs this current to the proper spark plug wire at the correct time, creating the spark at the plug. Without these wires, no car would even turn on. Don't trust just any replacement part for your 1977 Firebird, use what came on your car when it left the factory.
