I am working on a well butchered 74 Road Runner wiring harness. Lots of wires are flat missing.

This car has cruise control from the factory and for the 71-74 B bodies the cruise unit mounts where the windshield washer reservoir normally mounts.
This means the Washer bottle is not only different it is on the other side of the engine bay.

There is a brown wire for the washer motor connection laying un-connected near the cruise control unit.
How is the washer bottle on the other side of the engine bay wired?

Is it another wire in the harness that I am missing or is there a separate wire/harness running across the engine bay like the AC wiring is wired?

Anyone have a 71-74 B body with cruise?

Thanks

Bryan
