Usually when you want to add an ancillary electronic device to your engine management system, it involves gathering spools of wire, cutters, wire crimpers, connectors and terminals, and then cutting and splicing into the harness. And seldom is the harness easily accessible, which makes the task even more laborious.
To make adding devices like turbo timers and data loggers to your system less arduous, AEM offers the ECU Patch/Extension Harness. It eliminates the need to cut your factory wiring harness to add ancillary electronics and provides easy access to all ECU signals/wires. Removing ancillary items when they’re no longer needed is also simplified with the Patch/Extension Harness. To make the wiring process easier and facilitate troubleshooting, the harness is designed for out-of-car access. And you won’t have any connection issues because the harness is constructed with original ECU and harness connectors to ensure exact fitment.
The ECU Patch/Extension Harness is backed by a limited 1-year warranty against defects in materials and workmanship.187.32Brand: AEM Part Number: 30-2988 UPC: 840879019624 This part is compatible with 32 vehicle(s)
John Concialdi and Bob Sullivan co founded AEM in 1987 as a tuning performance shop in Compton California. Both men had extensive technical backgrounds in engines and engine airflow, and in a short time AEM became the go-to company for performance modifications. By 1993, when the company relocated to Gardena California, it had become commonplace to see cars wearing the bright yellow AEM logo winning races. AEM tirelessly dyno tested and worked closely with racers and auto manufacturers in an effort to understand intake energy dynamics. This resulted in the sale of their first air intake kit in 1994. AEM can boast a number of firsts and unique products: They’re the first manufacturer to make an intake system with specific tube lengths and diameters to take advantage of pressure waves in the inlet tract; they developed the first dual chamber intake kit; they designed an air bypass valve to prevent hydro-lock should the air filter ingest water; and they created one of the first hybrid intake systems for modified cars. AEM continues to create innovative products to help you get more power from your car.
