I cleaned out my PM box, please re-send your message -I have been without home internet for a few months thanks to a bum antenna for my wireless provider. I can't check webmail at work -I could use my phone but it takes forever.

I sat down with schematics and diagrams from the workshop CD last night. After about an hour, I think that I may have worked out a fair solution. One that will settle my desires as well as be easily installed and removed by anyone with fingers. I'm also looking at a 4hi only option as well (VehiGaz).

Just for kicks I looked up the TOD patent, just to see if there was some additional information that would be helpful. Wow. This is one impressive piece of engineering. It's patent #4,989,686 dated 5 February 1991 for those who care. There's tons of info in there, also some diagrams which I would really like to see (logic flowcharts, schematics, graphs of various clutch command signals). The patent also confirms the suspicion of a PWM signal from TOD to clutch, as well as a feedback signal from clutch to TOD.
I could not view the drawings however. If anyone can figure out a way to view them (free), please snatch them and post them here -if it's legal.
