Re: TR upgrade question
The second drawing is the most accurate one in the post. The first is just plain wrong and the last one is for a ford. However, the first one is tailored to the 1978-79 model years. I am sure it is very similar but you should match the color of your wires to the diagram to make sure
The upgrade is easy to do. If you buy pre-made wires, the whole thing should take less than two hours. 75% of your time will be making a bracket for the new coil. It may be worth your time to go to a yard and buy one.
