Hello guys. Im doing a swap on a seat ibiza 6k2.

I have the engine AQX code and its harness.
I connected the harness inside, wich is all colors with the same colors (from what i saw when i was removing the 1.4 engine harness)
But i didnt change yet the ECU. It is still the 1.4 ecu
When i try to start the starter, so i turn the key to make it spin, it doesnt do anything, all i hear is the relays doing this bzzz sound.

Any ideas how i can fix this ? Please help
