At this point, you should probably go with DBI D2D between the Avital and the DB-ALL2. While I don't use DB-ALL2's, I have heard
they work OK. We will assume this is correct and do the entire install as DEI, the manufacturer of your chosen modules, wants it done.
First, you should find a way to verify which firmware is loaded on your DB-ALL2. If the EBay seller thought you have a G key vehicle,
it would be flashed with TL2 firmware. That would be my main concern. Being as it is kinda working, it might indeed have the TL1
firmware and it's just your duplicated control that is confusing the issue.
Next for the wiring. We will go for the basic, bare minimum wiring.

Starter2 relay :
Relay Pin 85 to Avital Remote start ribbon harness, Pin 5 PURPLE (-) 200mA STARTER RELAY TURN ON
Relay Pin 86 and 87 to Lt Green @ ignition switch, white 8 pin plug, pin 2 through 7.5 Amp fuse
Relay Pin 30 to White (+) @ ignition switch, white 8 pin plug, pin 1
Wire connections from the DB-ALL2 to the RAV4 are shown in the Type 1 diagram in solid Black lines from the left side of the module.
Only 6 wires to connect from the DB-ALL2 plus the D2D 4 Pin harness.
As you can see, it's pretty simple. Four wires are needed on the Avital H1 harness, none on H2, none on the 3 Pin Door Lock harness,
only one wire on the Remote Starter Ribbon harness, none on H3 and all the wires on the heavy gauge relay satellite module.
As mentioned, it is possible that the Avital can not handle the Tach and/or the Brake signals via the D2D harness. If you can't get a
successful Tach Learn on the Avital after the DB-ALL2 has been successfully programmed to the RAV4, you can hard wire that signal to
the Avital from either the DB-ALL2 or the OBD2. Same thing for the Brake signal. If pressing the Brake Pedal does not shutdown the
remote started engine, hardwire that input signal to either the DB-ALL2 or the Brake Pedal switch.
Soldering is fun!
