Can someone PLEASE recommend a trusted, reliable U.S. source for the "Yellow OBD Adapter" our cars require? Many of the adapters I see for sale on Amazon and elsewhere have VERY poor reviews, including reports of adapters that are wired wrong and some that don't work at all. Prices vary a lot too. Such posts even appear on this forum. Can someone please refer me to a specific retailer and/or brand name? THANKS!
