A/C wires not an option on new wiper harnesses for 68 barracuda - where to find?

Called Year One back. Different rep. but same response. They don’t do custom orders for harnesses and don’t sell individual parts for making up your own modified harness.
They said they have never done so. They also said they only make what they have blueprints for from Chrysler.
So struck out with Year One on an a/c harness and both they and MH won’t sell the parts to do so and MH won’t do a custom harness now- maybe they did back in the recent past- idk
I will contact Evans and see what they can do
