If not, you'd need something like this -- maybe exactly this: http://www.jegs.com/InstallationInst.../249-82085.pdf.
Ok, I understand, which is a miracle in itself when it comes to wiring. The Zex unit would have been ideal, but they don't make it anymore and I searched for days and couldn't even find a used one, so I went with the MSD rpm switch.

Huh. That sucks

Actually, now that I think about it, load (or TPS), engine speed, road speed, and knowledge of how that breaks down for each gear will give you the values to plug into whatever window switch device you use, so this can definitely be done with the right controller

Zex window switch just counts the number of times rpm hits ur upper shut off rpm before it will engage at lower limit 3rd gear spray would be upper limit reached twice then its on does mad not make a "skip shift"?

Are you sure no one has any in stock?

I got a bunch of hits googling the p/n -- it might be worth calling around to see if anyone has it in their inventory.

Hey Jordo,
I called and searched everywhere and the only guy that has one is RPM outlet and wants $400.00 for it. I'm not so desperate that I'm willing to pay double. I do appreciate the help!
Figures, they were the only one I DIDN'T call because of the price, they have two!!! Now I sit here trying to decide, send back the MSD digital and bite the bullet and succumb to their demands!
