I am hoping to mount it in the knockout panel to the right of the wheel next to the dash light dimmer knob. I figure I can wire it to the "mist" button wires. I'll report on success or failure when I get it installed.
I just took the time to scan this entire topic. It began as a question about intermittent wipers for the Pickup--specifically a '95, but should be the same for '88-'95. It morphed and got onto the same question, but for P'ups ('81-'87). This is a subject where the answers are completely different, depending on whether the question is about the Pickup vs the P'up.
Now we're back to the Pickup. I've since bought and sold a 1st gen Amigo, and now I know a little about the intermittent wipers for it and the Pickup (they're identical). To get intermittent wipers using factory components, you need the switch cluster and the relay. On this truck (unlike the P'up), the wiper switches are not on the turn signal stalk. They're in cluster in the dash (right side of the panel, if I recall correctly). The non-intermittent switch is momentary, and I think it is labeled "MIST". The intermittent switch toggles on/off, and I think it is labeled "INT". It's not a hard swap. The parts could come from a Pickup or a 1st gen Amigo or Rodeo.
The factory intermittent feature has a preset interval. Your aftermarket add-on probably allows you to adjust the interval.
