This adapter harness is a lifesaver for GM V8 owners! Installed it in minutes, and it works flawlessly with my Silverado’s throttle body. Perfect fit, no splicing or guessing—just plug and play. Great quality wiring and connectors, exactly as described. Highly recommend for anyone upgrading or replacing their throttle body on compatible models. No issues with performance, and it saved me from buying a whole new assembly. A must-have for the right application!
