Every AutoTech Engineering unit is assembled 100% in Riverside, California. With over 100 years of combined, “on hands” experience and the fact that we have been in business for over 28 years has allowed us to source and supply the highest quality component parts to ensure your unit exceeds expectations. All are plug and play unless over wise stated.   NOTE, these come supplied with our 14.8v bypass so you will have a dash light AND WE DELETE 1 FOOT BUT FIT.
