    My new ECM BCM module etc place to shop!

    Truly re-furbished ECM not all refurbed electronics are refurbed. Easy process to order with a slight confusion on when to supply the VIN#. Unclear if it was VATS ready for our vehicle and that important info was not communicted as well as that even though its plug and play you will need a scan tool that can command modules and sensors. However,,,we thought too much as Auto101 did everything and all we had to program was can crank correlation. A sheet with instructions should be uncluded for those who are not shop savy. Overall communication was my gripe. Product, speed of shipping and programming and product appearance and function are all OUTSTANDING!!!
