I did the nutter bypass a few years ago. They talk about the purple wire going into the open or "C" position. I see nothing that says that. Here is what they say. I am confused about it.
To install jumper wire, remove the two (2 and 4 pin) connectors from the ignition
module located under coolant bottle and raise connectors and harness to locate 4-pin
connector. Release connector lock and install jumper wire in the open or “C” position of
the four-pin connector. Close lock and feed jumper wire through harness to junction and
splice into 18 (purple). Re-connect 2 and 4 pin connectors to Dura-spark module
