Default Blinking Check Engine Light on MY00 RS with MY02 WRX Swap

Ok, I have a serious annoying problem with my 2002 WRX swap in my 2000 RS Coupe...

I get the annoying flashing Check Engine Light and the fans turn off and on when the key is in the ON position...Not when the car is running...

This is supposed to happen when you are diagnosing the car thru its Diagnosis Port in the inside, under the steering wheel...

But, I don't want to diagnose anything and I can't see where the wires may be shorted...

Anyone know where I should look and what I should look for?

Thanks for any advice or direct help,

It sounds like at some point when you were working on the car, you connected together the green plugs that are underneath the dash. Those plugs are normally left disconnected and when plugged together will activate a diagnostic mode that does exactly what you are experiencing- flashing CEL and constantly cycling fans. Go under there and check, you will probably find the green plugs connected, unplug them and all will be fine.
