Hiace 2.7l 2010 A/C not working

Hi

Customer brought to me Toyota Hiace 2.7l 2010, with ECU burnt and replaced by one from Toyota hilux 2.7 2010, it is run and drive with no trouble unless the A/C does not work .I reviewed and compared A/C amplifier wiring with the ECU and found deference in communication between two ECU's (original and installed) with A/C amplifier as shown in attached pic....old ECU connected to Amplifier through CAN h and L but in installed one is through AC1 and ACT .

Is there any way to modify this wiring to make correct communication to make A/c working properly?

Note: A/C compressor runs when connect it directly to battery.

thanks
