Timboj Posted July 12, 2022 Report Share Posted July 12, 2022 This isn't a tuning question but couldn't find a better home for it. Anyone familiar with the early 350Z VDC knows that the OEM VDC button basically reduces its impact but doesn't turn it off completely. There are a few forum posts and YouTube videos about installing a switch to successfully cut power to the VDC unit, although there doesn't seem to be common agreement (or just indifference) on whether to splice the switch in power or ground. I'm of the understanding that it's better practice to cut power as allowing power through but cutting ground increases the chance of shorting/surges. Is one option better than the other or doesn't matter? Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 13, 2022 Report Share Posted July 13, 2022 Yes I would place the switch in the 12V supply. The main ground is often connected to a common ground plane internally for grounding other devices such as sensors etc, so if you cut the main ground you can end up pulling high currents through a sensor that wasnt designed for it.
