Fabtech-Performance Introduces Our new Plug & Play Injector Harness’s. Save yourself the hassle and potential Catastrophic failures that you can have by using the Cheap plastic Square connectors that are sold with most other Bosch Injector Kits to help increase Profits. Our Harness connectors are extra long so you do not have to worry about pulling on your engine harness to make the connection. They also lock in place once they are secured for a piece of mind.
