Question about CAC pump

[GNVenom]

Hello all,
I have a question. The CAC pump is controlled by the ECM, and I'm working on an XFI conversion, so my question is,
Can I use the fan control to address the CAC pump? My thought is use the engine coolant temperature setpoints to turn on the pump, which as I see it should run most of the time anyway.

Am I making any sense??


Thanks,
John Spina

Just wire it to come on with the ignition.

The 749 ECM (factory SyTy) CAC pump controls are controled by the electric fans parameters (as use other applications). So yes you can do that.
