The EFI relay is part of the integration relay, which is the black chunk under the EFI fuse in the under hood fuse panel. The wiring from the ECM to the coil of it goes from the ECM connector (against the passenger side of the firewall) to the connector under the bottom of the integration relay.

The wire to the coil is the gray wire in pin 2 of connector 1A.

It is the same for the 1NZ-FE, 2NZ-FE, and 2SZ-FE.

I was thinking about place where to install immobilizer and came to this connection http://xmages.net/storage/10/1/0/3/f/thumb/thumb_104f0111.png (http://xmages.net/i/3250954) and the origin http://xmages.net/storage/10/1/0/9/8/thumb/thumb_5a3031fe.png (http://xmages.net/i/3250957)
Immobilizer relay is "NC" default and when protection switch is on "NO".
Won`t be a deadline for engine and ECM when protection will switch ON while engine runing? Protection is working on car movement. Or can advice me a better connection. Sorry for my english :rolleyes:

NO for protection and NC for normal operation is correct for that wire.
