NO Start issue after Engine swap, HELP!

OK this will be some what lengthy inquiry.

I acquired a 2002 Boxster S with inter mix issue with 87K miles. Replaced the engine with a 2003 model Boxster S with 78K. The donor engine came from a automatic car. Following the Pelican Engine swap advice. Looks like I need to upgrade my ECU to 7.8 from 7.2. I got one from Ebay.

Also I have to source a manual wiring harness from a 2.7 Manual 2002 model. Only modification I did to the wiring is the transmission back up light connector from 5 speed to 6 speed. Wondering why I did not use the old one is because I want to keep the old engine intact complete for resale.

Now mostly got the car together and me and my son trying to start it and the response is not even a crank, dash are all lid up and engine failure appears on the dash. Atempted to hook OBD2 to view error code and failed to connect. Tried two different code reader and both failed to connect. All fuses are good and battery is over 12 volts, no help from battery charger in start mode.

I need idea what can cause this mode on Boxster, looks like security related?

Thanks in advance.
