1999 Ford Ranger engine ECM this is for a Ranger with a 4.0 L engine and a 4X4 automatic transmission. This was removed from a running and driving pickup it is in great use condition and ready to install. Some of these ecms require a flash or programming when installing a new vehicle to function properly. I am not sure if this is one of those or not but if so that is the buyer's responsibility to have done when installed. Look at all of the photos, what you see is what you are buying and will receive. Please ask any questions before purchasing and be sure to check out my feedback and buy with confidence! Thanks for looking
