There is nothing up the A pillar for the immobilizer ie the Pats. But you are using the full loom with the active anti theft system.

Now this is just a guess as I don't bother with the full loom, you are missing somthing for this.

No information on security is published in a Haynes manual.

My recommendation, ditch the full loom and run the ecu as a stand alone unit.

I may be prepaired to help.
