1979 Electrical & Wiring

Vehicle wiring is made of copper and shielded in a protective insulating sleeve. This protective sleeve is designed to keep things like oxygen and moisture out. Over time, this insulation can break down, allowing the elements to enter the copper wiring. Exposed to the elements, the copper wiring begins to oxidize, which ultimately degrades the wire’s conductivity. And when electrical components in your car see this increased resistance, they can act a little funky and temperamental.

Tame Electrical Components with new 1979 Mustang Wiring

To make your Mustang electrical components behave, it’s a good idea to start by replacing all major vehicle grounding wires. This is commonly referred to as the “big 3 upgrade,” and includes replacing the wires that run from:

• Battery to Chassis
• Alternator to Chassis
• Engine to Chassis

The idea is to eliminate any corrosion in your 1979 Mustang wiring. If you’re experiencing problems with specific components, it can also be helpful to invest in a vehicle wiring schematic. This makes it a lot easier to trace wiring, test conductivity and replace any faulty wires in your Mustang.

Adding Accessories

The 1979 Mustang came equipped with a 60 amp alternator, which is tiny by today’s standards. This alternator was designed to handle the original vehicle power needs, but if you’ve added any accessories that place a higher demand on your electrical system, you could experience electrical problems. If that’s the case, it’s a good idea to upgrade to a higher output alternator. Plus, it’s never a bad idea to add a separate accessory fuse block for any aftermarket accessories.

An accessory fuse block makes it easy to identity aftermarket accessory fuses and allows for a clean and central location for all accessory wiring. Rather than having 4 or 5 different fused lines coming off of your battery, you can have everything neatly fused in one main accessory box.
