Neutral safety switch manual transmission

No adjustment is possible.

Neutral Safety Switch (NSS)
Mounted on side of transmission, this switch monitors gear position on automatic transmission vehicles. The signal affects air/fuel ratio, idle speed and EGR flow.

There is no neutral safety switch on manual trans. And we do not advise bypassing on auto trans. As this is very dangerous ! And will effect the drivability as listed above

Clutch Engage Switch
This switch is mounted at clutch pedal and signals ECA when transmission is in gear. Clutch engage switch signal to ECA affects air/fuel ratio and idle speed.

If you have a manual transmission, you may have a clutch switch. A neutral switch is for an automatic tranny. I'm not sure which one you have?

I don't recommend trying to bypass, that can be dangerous, especially, for a manual transmission. I'm not sure of the site rules about giving out that type info.
