Thread: wideband through AC pressure switch

    wideband through AC pressure switch

    Over the weekend i have been trying to set up my wideband through the ac pressure switch on my 2010 Holden ve ss commodore.

    i wired the wideband to the red wire with a black stripe and my afr histogram works so i assume that to be the correct wire, now when i have the wideband connected and the car running both hi and low fans turn on full blast. i can turn them off using the vcm controls.

    is there anyway to stop the fans turning because the ac pressure wire is disconnected and if i turn them off via vcm controls will they still turn on to cool the engine?
