I think I am WAY off base as far as help but I am trying. When taking a 6th gen Ford truck intermittent wiper switch and adding it to a a different 6th gen Ford truck you need the governor/control box. And the plug and play red adapter cable.
Two different types of windshield wipers, two different wiper switches.
Two speed wiper switches have a low & high speed.
Intermittent (delay) wipers were optional on 1973/79 F100/350's and 1978/79 Bronco's. Intermittent is not another name for low speed!
