## Description

ACDelco GM Original Equipment Pigtail Connectors are connectors ready to be spliced into vehicle harnesses, and are GM-recommended replacements for your vehicle’s original components. These original equipment pigtail connectors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Review: Better than others - Work great! Better quality than the cheap alternatives here on desertcart. These are like 14g wire compared to the cheaper alternatives which are like 18g wire.
Review: Worked perfectly on my 2018 3500HD - This part was a life saver. My 2018 Silverado 3500hd started running rough and I took it to be scanned. It read #7 cylinder misfire, after some research and a fuel filter change I narrowed it down to my #7 injector pigtail. #7 is problematic because it is located between the firewall of the vehicle and the exhaust which basically just bakes the wiring over time. I had called Orileys, Autozone, Napa, and the Chevy dealer trying to get this connector. The only place with the correct connector that matched mine was Chevy. It was on back order and was $250. All the other parts stores kept pulling up a completely different style and could not find the right replacement. I installed this in about 2 hours while leaving the negative terminals on the battery unhooked during installation. I made sure to put some electrical contact grease on it before clipping it back in due to the extreme temperature #7 is exposed to. Hooked the batteries back up and it runs better than ever. No issues so far, I would highly recommend this product.

## Questions & Answers

**Q: When do spark plug wires need to be replaced?**
A: The lifespan of spark plug wires varies based on factors including the climate and driving habits, but they generally last about 60,000-100,00 miles. Periodic replacement helps maintain the engine’s performance.

**Q: What are signs spark plug wires should be replaced?**
A: Common signs of wear can include a rough-running engine, possible misfires and even hard starting. Acceleration can be affected and fuel economy can decline. Visually, cracks or fraying of the wires are signs replacement is needed.

**Q: Are all spark plug wires the same?**
A: No. Material composition and design can vary widely, resulting in varying levels of conductivity, durability and electrical interference suppression. GM Genuine Parts and ACDelco Gold Spark Plug Wires meet GM factory specifications.

**Q: Do battery cables need to be replaced often?**
A: Generally, battery cables don't need periodic replacement, but they are subject to corrosion and other forces of wear that can affect their performance. This is especially true in climates of high humidity, where the roads are salted in the winter.

**Q: What are signs of the battery cables need to be replaced?**
A: If loose connections are ruled out, hard starting, a failure to start and other intermittent electrical issues are common signs the battery cables should be checked for corrosion and other signs of wear.

### ⭐⭐⭐⭐⭐ Cheaper than an injector!
*by G***S on September 22, 2022*

Like all automotive electronics, they're a bit over priced for what you get. That said, on the GM L5P Duramax engines the injectors are usually not the culprit when performance issues arise- the OEM connectors are often assigned the problem cause. These are easy to install (ditch the butt splices; solder them in if you can and shrink wrap the joint or use a quality electrical tape instead). They are not "polarity dependent". I carry an extra one or two just in case. Cheaper than replacing an injector and if you do need to do an injector change, put one of these on as well at the same time.
