problem here is if you daisy chain two units, when you tap "up" to stop
the down motion, it will go all the way back up!  No, the proper way for
these to work (IMHO) is a tap gets you full open or shut, a steady
application gets you just as much as you want.  Oh well. 

(I have the V8 info, thanks)

Coupe, 2 windows, switches in center.  one for each window.  makes it a
lot simpler.

I bet you're right.  Must take one apart now...

Is it up and down?  P/N?  Please.  And to think I had one here - maybe I
still have the relay, I'm sure I didn;t send it away with any installed
in it!

$ gets to be an issue too... that's why I would love to know of a relay
that will do what I want for certain and then chase down wrecks to get a
couple!
