Trying to diagnose non-working wipers and wondering if anyone can share what which terminals should "light up" on the different wiper switch settings. I suspect my motor is burned out, but want to make sure I'm not just going burn another one when I install that. Wiring's kind of a mess on this truck ('93 250)

Looking down the holes on the plug, numbering 1-4 left to right, I get:

Hi: 4
Lo: 2, 1
Del: 3, 2, 1

Sound right?
