Ive been in under the dash lots of times,not as of late due to back. The 67 had a 4speed in it when purchased. Its now a auto. There is a plug connector with a purple and white wire connected to 2 purple wires. They are in the harness that goes up to back of cluster and i believe branch off and come down to dr.side kick panel area. I appreciate the help everyone. BTW Red, i pulled the 2 wires up myself to get them out of the way, shift linkage,exhaust.
