When cars were built anywhere from 1960 to 1970, the last thing on GM's mind was that 40 years later we would put in high-tech stereos, alarms, headlights, and ignition systems. Therefore, fire caused by inadequate wiring becomes a problem just waiting to happen. To alleviate this, American Autowire (800/482-WIRE, www.americanautowire.com) and other companies offer wiring kits for just about anything. Although it seems like a lot of work, it's better to know that your car is safe with all the high-tech gadgets you want. The least you can do is to go through your ride and check out the wiring. Be especially cautious for wires damaged from burns, insulation melting, failed factory connectors, and firewall plugs. Also check the OEM fuse box to be sure that the terminal connectors haven't been loosened. If you run across any of these issues, be sure to fix them properly; don't use electrical tape and wrap stuff together.
