Thank you for the feedback. I was trying to find some old pics before the 70 Dart was torn down, Here is a pic that I initially thought it went over to the wiper motor stud. But the wire that was spliced may be the blower motor wire, it's difficult to tell.

Unfortunately, I do not have a photo depicting the right side of the engine compartment (up close). I only have the pic from the online ad, but it's too difficult to make out the actual routing with all the pluming going on.
