Hi, I'm installing a tach, oil pressure, and water temp guages on my tta. Where do I tie in the sending units? Do I uninstall the factory sensors, or will that mess up the ecc? Im planning on changing all guages for aftermarket. I'm also installing a boost guage, I know where to tap in for the boost, but I heard if I disconnect the factory guage it will mess up my ecc? In an earlier post it says the green wire by ac blower, is that correct? Any help will be appreciated. Thanks.
