I've installed a B&M Tork-Master 2000 converter and a B&M "Sift Improver Kit" 
set up for RV/towing. I'm looking for a fun daily driver that can haul a 
rock-crawler several hundred miles. But these few things have got me 
confused. So, you say to leave the valve body as is, but allow the ECM to 
supply the (-) ground to the sol.?? Using a type 10 harness (or modified)? 
And I assume eliminate the vac. switch but keep the brake switch.

Or, even use the Type 1 set-up where the +12v is supplied thru a brake switch 
and then a vac. switch, and the sol (-) ground is connected directly to the 
valve body?. If I do that, does the ECM not even acknowledge the 
transmission, or does it need an input from the trans?(i.e.  change spark 
table for 4th gear?) In this circuit will the stock vaccum switch operate 
properly with a slightly cammed engine?

I'm just trying to understand every-thing I know, and set this thing up right 
(if there is a "right")the first time... the most simple way would be great, 
too, for now as the fuel and spark things are going to keep me up late enough 
at night. I'm open for suggestions on what to set the TCC lock values to in 
the EPROM, or should I leave them stock? I'll stop there for now. thanks for 
the insight.
