I am repairing and upgrading my engine harness on my 68 chevelle using a 69 wiring diagram found on this forum, The 69 doesnt show a ac circuit but thats ok since so far I think everything is un molested on the ac circuit anyway. But the diagram shows a orange wire coming from the left side of the bulk head connector going over to the blower motor, my car has a orange wire coming from that location but is cut off around the distributor firewall gutter harness and the it looks like all my ac wires are in place. Does anyone have the 68 with ac diagram that show something different? If not I need to return to the ac circuit and look closer. Thankshttp://i62.photobucket.com/albums/h115/bigcedarfarm/69diagramwithpointer.jpg

That orange blower motor feed wire is not used on cars with A/C
It's just left sorta dangling.
I couldn't figure out what is was for on my car either until someone here told me.

Thank you!
This is good to hear now I can focus on the other wiring
