WHY TO BUY?
Just like nerves in your body, your vehicle contains a wiring harness that relays messages and controls engine activity to keep everything running strong. Over time wiring harnesses corrode and break which can cause total engine failure. If you have a broken harness or perhaps suffered an electrical fire you can remedy this problem with a brand new Hummer H3 engine wiring harness. Aftermarket Hummer H3 engine wiring harnesses are plug and play so that you can easily get your vehicle back on the road where it belongs. Here at Andy's Auto Sport we have a great selection of Hummer H3 engine wiring harnesses for you to choose from. So no matter what your needs you are sure to find the perfect harness for your application in our expansive catalog.

DID YOU KNOW?
While our assortment of Hummer H3 engine wiring harnesses is great for OEM replacement and restorations, there are also a host of custom harnesses available for those who are building race cars and show cars that have been dramatically altered from their original form. And if you are thinking about doing an engine swap it is also possible to make one of these custom harnesses work for your application. Because they feature high-quality connectors and terminals you can avoid butchering your wiring and reduce the risk of electrical fires. These professional grade wiring harnesses are a great way to sort out your project.
FAQs
Q: What is an engine wire harness? Why buy one?
A: Your vehicle has lots of wires in the engine bay and under the dash board. These wires are crucial for controlling the functions of your motor including the ignition system, gauges, engine management and a host of other functions. If you are working on a restoration project, have added aftermarket ignition components or electronic accessories, or have suffered an electrical fire one of the best available options is to step up to an aftermarket engine wire harness. These harnesses are designed to simplify and cleanup the wiring in your engine bay for a great aesthetic every time you pop the hood. They feature color coded wiring, well designed fuses, and circuit protection to ensure that your system remains protected from short circuits and power surges. With an aftermarket engine wire harness installed you will have a clean and reliable electrical system that will keep your ride running smooth for many years.
