Hiace 2010 2.7 l A/C not working

[znn]

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
