I purchased the 5L5A-12A650-AUA ECM for my 2005 Mazda B3000 and was really impressed with the whole experience. The unit came VIN programmed, so installation was straightforward without any hassle. Their team kept me informed throughout the process and responded quickly to my questions, which made me feel confident about the purchase. Shipping was also very reasonable, arriving faster than I expected.
