I would call DEI Tech Support on that one. According to their supported functions list, the DB-ALL only handles the transponder bypass function for the Tacoma and nothing else. The DB-ALL seems a bit overkill in that application as there are other bypass modules that will do the same for less.
The solid Orange light during programming is correct if the DB-ALL does not support the HSCAN bus for that vehicle. The HSCAN connections supply all the Status signals and the Tach & Brake signals shown in the Type 1 install diagram from the 12 Pin connector.
As a guess, if you wanted to use the DB-ALL as a transponder bypass only,
in D2D mode the only other connections required are :
DB-ALL
10 Pin
Pin 9 Pink ---> Heavy IGN1 @ Remote Starter which continues to Ignition 1 @ Tacoma
12 Pin
Pin 7 Gray/Black ---> DB-ALL 10 Pin connector, Pin 9, Pink wire
Pin 10 Yellow/Black to Tacoma Transponder 7 Pin connector, Pin 5, Light GREEN/ Red
Pin 11 ORANGE / Black to Tacoma Transponder 7 Pin connector, Pin 4, Pink/Green
Not sure how the Type 1 module programming would go without the HSCAN connected...

Soldering is fun!
