I want to use pin B8 for my input for the high/low boost switch, however I would like to know if pin B8 requires a positive 12 volt from the switch or does pin B8 just need to be grounded from the switch. How do you recommend it be wired. I know the clutch switch for the launch control using pin D4 just needs to be grounded. Is pin B8 the same. It would really help if the S300 help page explained how to wire some of the options that can be selected for inputs.

Is there a way to tell which pins need a positive input or ground?

Thanks

B8 (PSP) is a grounded input (just to be grounded from a switch to activate).
