Hi, David Neidl here, I have an extensively modified Bentley Arnage T, 2002. The factory trans was discarded to allow for an all wheel drive convertion and the body was altered by Genaddi Design Group.

I have the trans working in all functioning gears with default shift patterns using a PLC provided by powertrain control solutions, and now i have to enable the speedometer operation. I need the wiring diagram for the cluster (speedo) and if you can find out what type of signal is used to drive the speedo, is it a stepper motor type or variable voltage type- can I get a signal wire at the ecm/pcm.

Also I need same information for engine coolant temp.

I also need to know where to tap into to get an engine rpm/tach reading for the trans control module, what type of signal is it, digital or analog?
