techguy, that is the one I have. I purchased it and the windshield wiper module from you a couple of years ago. I installed them in my 82 300Dt. The wiper module works fine - as far as I know, but the tach amp is what caused my tach needle to peg to the right when the horn was activated, and twitch (haphazardly) with the turn signal light. Of that I am positive.

Any chance of being able to purchase one of these ? or grab a schematic so i can build my own ?>

please

Why would you want to build your own? You need the firmware also for it to work.
