1990 Mustang Electrical & Wiring

Your 1990 Mustang's battery, ignition, and lights all rely on your electrical system and wiring to function. But if your wiring has been damaged, you might find your lights start to flicker and your battery ends up drained.

If you've already pinpointed your electrical issues, then check out our selection of individual fixes. Repair plugs and harnesses will help you get your issues addressed. Or, if you want to upgrade your wiring entirely, check out our wiring kits. Many modern wiring kits offer features like cloth wrapping. Cloth wrapping can help keep your electrical wiring safe from cuts and breaks in the future.

You can also upgrade your Fox Body Mustang to an electronic fuel injection system, with help from the harnesses available. Though wiring is one of the tasks enthusiasts are reluctant to take on, with color-coded, ready to go, systems, it's easier than ever before. You'll even find options designed to help with race builds.

Shield, replace, upgrade, or repair your Mustang's electrical and wiring system for performance you can count on.
