My car is a my94 wrx wagon, was an auto now a manual, where do i find this switch? Is this switch the original one from the auto box? or will it have been replaced to match up with the 2003 5 spd box now installed?
Thanks

Also it is throwing up cels frequently, could this be a cause of misfire?

I know nothing about a NPS on an auto box. On a manual, it has a NPS in the side of the gearbox, on my classic it's on the passenger side, close to the top (i.e. hard to get at unless on ramps). It simply sends a signal to tell the ECU whether it's in neutral or not. I had a fault with mine and replaced it, but I only knew it had gone wrong because my Power FC showed me that it was clicking in and out randomly. TBH it didn't make a single bit of difference to how it ran. Although perhaps on a standard Subaru ECU it plays a more significant role?

I would guess that your new manual gearbox would have had its own NPS supplied with it rather than reusing anything off the auto box.

I thought the manualbox might have had its own nps, but is the auto loom different to a manual loom?, i know my auto ecu is different overall to a manual ecu?

I would be very surprised if the auto box used the same gearbox loom and sensors as the manual.

Thats true, so what would have been changed in the conversion? the cars entire loom?
