Thats not the only difference. The bigger difference is that I know how to use the search function. Also, if the car ran, its not an immobilizer problem. The car can NOT start without that wiring done correctly, no chance.ok
I guess the only difference is that my car is actualy swapped and ran about a week ago and was going to go out to some events this month.
And oh look, a '07 sti pinout by brydon himselfthe immobilizer system on 05+ STi consists of the ignition key, the ecu and an immoblizer unit (box). all 3 components must either be out of the same car or reprogrammed at a dealer. you'll also need the antenna/receiver for the key which is integrated into the light surrounding the key cylinder.
the 04 STi is also throttle by wire
you can use an 04 ecu to bypass the immoblizer system but if using an 05+ harness a few pins need to moved on the ecu end.
