Is5700

Already found him thx , and yes it seems a signal generator is all that's required to make the Ac think the engine is turning ( hopefully)

Hi everyone , I've just completed a ls1 6 speed conversion, in a 2001 is200 everything works perfect , only issue is I can't get the climate control to activate the a/c compressor. I'm assuming it's because the can bus can't see the original engine turning over. The original ecu is still in place so it can transmit water temp and battery data to the dash, I've tried sending a pulse to the ecu via the original cas wiring but it didn't work, I'm open to suggestions, worst case I'll fit a new a/ c switch but then the climate control won't cycle the compressor when required to prevent icing of the evaporator ?
