I bought the reverse harness which plugged into the tranny no problem.  There are two male ends that are bare and a plastic cased end for a third.  Car is about 40 miles away so can't remember if that third one in the plastic connector is a male or female.  
The plastic connector is the one I am questioning.
The good news is the mechanic at a contractor's firm I know is a retired 70 YO former mechanic from a Chrysler Plymouth dealer.  He is out of surgery today and while off said I will be the one under the hoood connecting the wires.
Driveshaft is coming from CO.  Williams recommended a firm and they said I should have it by late next week or early the following week.
Any idea on a non twist top good looking black battery that the old style battery hold down will work?
