Well, nothing ever goes as easily as you hope it would. I bought this TCI trans control unit or TCU. I got it brand new with wiring for 500$. Now I know why! I knew it was the earlier model, but what I didn't know was it needs to have a tach signal from a distributor type engine and diesels usually use the alternator. Well, after a bunch of freaking out I did a little research and found out that dakota digital sell a diesel tach signal converter that is completly tunable. 65$. Ya hoo! Now I have to hurry up and wait. That is the last piece of the puzzle hopefully. I hope I have it fully functional on thursday or friday.
