Pin #104 comes from the factory with a black GROUND wire connected to it. My instructions make it very clear: you MUST cut that black ground wire completely OFF of pin #104, don't just tap into it! If you leave the ground wire connected you are also grounding the starter interface relay, as if the clutch is OUT, so the car won't start. The TMO instructions are misleading, because Todd used one of those vampire clamps to attached to the wire on pin #104. But, if you READ the instructions, you will see that he tells you to cut it off.
TMO Clutchwire instructions
"Peel back the black electrical tape on the harness a couple inches for some working space. Then cut the wire about 1½ inches back from the plug."
When he says "cut the wire" he means CUT IT OFF and leave it disconnected!
