what version of t-link do you have. If its the older DOS version, just run the supplied cable from the ALDL port to the printer terminal on the laptop. Load the program to the harddrive, and setup a shortcut to it on the desktop. If it the new windows based version, you have to run a test procedure to the cable to make sure it is working before it will link with the ecm. Instructions are in one of the files on the windows based version, dont remember where exactly.
