btt anybody? even a stab at it, will take some logical guess's
heres mine my guess is it could be from another ecu that has been plugged in or some form of diagnostics connector??
would really like someone to confirm it tho

Been a while 
Got back onto this subject after talking to someone who does rally prep to see if they have come across it, and he thought it was strange
Basically he was under the impression for ah 96 v3 Sti, it should have 4 yellow connector ecu ???
Basically he was baffled when i removed it and there is 3 yellow and 1 white, opened up the ecu and there is no piggy back chips so 2 Questions that i'm intrested in
1. What is the proper ecu for a 96/97 V3 Jap Sti?
2. What is the spare connector for thats currently pictured above for ??

That connector is the common connection for the earthing from injectors, sensors et al, it is essential to have it in place but its not "spare".
Your three plug ecu indicates the car is a MY97 not a MY96, bear in mind that a MY97 car ran from Sept 1996 to August 1997. So your man is not correct.

judging by the sound of this I WOULD UN-BOOK your car as this chap does not have a clue! its not just a case of downloading a map form x y z for and loading it on, the only way that your ecu is mappable is by fitting it with a standalone ecu which down you way would be best a simtek from the engine tuner.
