Gtir Neutral Switch

Hi

Wonder if anyone here knows the answer to the following:

Neutral switch has 4 pins

1. Ign 12v

2.Ground

3.To reverse lights

4.To ECU-neutral switch signal

Not sure what the neutral switch signal is for, i have been informed that this was used by the oem ecu to help control idle. Does anyone know if this is correct?

Do i need this bearing in mind i will be using the oem iacv with emumaster black.

Hello you will not need it connected at all with the ecu master ecu

but it was needed to help idle control with oem ecu

Regards Ross

Thanks,i will just connect the reverse switch aspect of the plug then as its 2 in 1.

Would you say the same applies to the power steering oil pressure switch aswell?
