You're probably here because the Chinese-made injector adapter harnesses that you paid $50-$75 for fell apart. Sorry you had to go through that.
SpoolinUp adapter harnesses couldn't be more different. The Japanese made OEM Connectors and Silver Plated Mil-Spec Tefzel Wire are assembled in-house. The result is a product that exceeds any on the market and still costs less than the "competition" (we use that term loosely).
