1. The clutch switch allows the ECU head unit to know when the clutch is depressed and thus when to activate NLTS As described in the section Hardware Requirements on page 3 this feature requires that ECU head units with serial numbers of 2000 2099 be updated to match the hardware available in later units Assuming you have an updated or later version of the head unit there are two cases 1 1990 1999 DSMs the clutch switch wire must be wired up manually independent of whether or not you own a PnP ECU 2 2003 2006 EVOs the clutch switch wire is already wired for you on PnP ECU s or must be wired manually on wire it yourself ECU s The clutch switch wiring is described in section 5 5 8 of the ECU user s manual Page 12 8 2 The External Switch As with the clutch switch input this input is not available on ECU s with serial number 2000 2099 unless the hardware has been updated to match the hardware on later models of the silver box To external switch input is a 5 volt input that allows the ECU firmware to switch between two sets of fuel and timing maps based on an external input This input can come from a physical switch or the output of a controller box for nitrous etc This always needs to be hand wired on all ECU s The external switch wiring is described in section 5 5 9 of the ECU user s manual 8 3 The Simulated Front O2 Output The simulated front O2 output allows the ECU to generate a front O2 signal2.
