A/C Idle up rpms for 1uz swapped Cressida

The 1UZFE EGR Delete Kit is available for sale here.
I have this 1uz swapped cressida and it has a 95 ls400 engine

I merged the factory condensor and drier , with the ls400 compressor , and the a/c blows cold. My issue is when coming to a stop the idle is super low so the alt stops charging and, when hot sometimes oil pressure drops to nothing.

Has anyone found a solution in regards to achieve a higher idle with the a/c on . I know the lexus has a separate computer that triggers the idle up in the ecu. the cressida does not. I tried to wire in a evap solenoid with the power from the a/c clutch, it did idle a little higher but not enough.

any suggestion would be much appreciated Thanks
