Need Help with 2NZ ECU pinout

Dears , i need help with an 2NZ ECU Pinout , the story is that i did an engine swap for my Echo/Yaris ( model 2000 ) from the 1SZ 1.0 to 2NZ 1.3 , the problem is when i got the new engine i found that the ECU sockets is different from my old one , the first Pic is for the old ECU and second Pic is for the new one ( the pic is not mine i found it random from the internet while searching but it's the same like mine ) , the problem that i can't match the old wiring system coming out of the dashboard to fit the new ECU , also some problems like that engine Tep. lamp is not getting the right signal as My car is with the digital Dashboard so the Temp. is a lamp not an amber one , the big problem that when i try to connect the Diagnose device to do the diagnostic test the device is not responding which mean that the socket is not connected rightly , and for sure the Check engine lamb is not responding too

so i am looking for this ECU pinout as all the Pinouts that i found for 2NZ look like the old socket ECU not this new one , I got the engine from the dealer as it's for Toyota echo/yaris 1.3

can any one help me out with this !

For the 2nd generation Yaris, the 1NZ and 2NZ have the same pinouts, but for the 1st gen it appears that they are different, since the ones I have for the 1NZ don't match the connectors on your 2NZ ECM.

I would recommend subscribing to the Toyota Europe technical site to download the ones you need:
