Finally a true plug and play B-Series/FT-450 harness
This harness is built tough. The craftsmanship is excellent. Everything that's labeled is, and it makes everything that much easier when plug everything in. Top notch work made in the USA. Comes with instructions for some guidance. I ordered the B Series tucked engine harness, Honda/Acura fuel pump harness and dual fan relay harness. I did a test run and so far, on the engine harness, every plug worked with its corresponding sensor and all the injectors plugged right in. The Fueltech harness plugged in no issues and both harnesses had all the correct connectors to plug everything together. I can't wait get everything back together so I can finally fire up the old hatch after 10 long years.
Thank you again Ricardo for all your help and all the gifts you left. Please keep up the quality work and the excellent customer service. I will be getting touch in the future about my wife's 82 Civic wagon that's getting swapped in the future.
