Public Service announcement EFI NSS pin 30
Maybe this will come up in searches.
This is the most screwed up item going when installing EFI..
Pin 30 is the NSS ( neutral safety switch) when the vehicle came from Ford it is installed to tell the EFI computer that the vehicle is in neutral. Ford did the connection using the O2 harness if you have a nice factory O2 on the part number tag it will say manual or auto under the part number. so if you have a manual computer you would need the correct O2 harness to match.
If you look on a Ford wire diagram http://forums.corral.net/forums/showthread.php?t=1174340 you will see it is broken down to to 2 options Manual and automatic transmissions. the transmission type is not a factor when hooking up EFI.. let me say that again... the transmission type is not a factor when hooking up EFI. once more in case you missed it.. the transmission type is not a factor when hooking up EFI.
The computer code is what dictates how to connect this up correctly.
Ryan has already done the homework look it up http://fordfuelinjection.com/?p=17
here are 2 examples A9L& A9P
A9L this is a manual computer pin 30 (NSS) will connect to pin 46 (sig rtn)
A9P this is an Auto computer pin 30 (NSS) will connect to ignition start wire
now just in case your uncles brother-in-laws sister second cousin was a Ford tech and told you that pin 30 does not need connected or modified when swapping in a motor and you go ahead and start it and anyway here are possible issues.
Computer will not return any codes when connected to a "scanner'
there is code 67 when you do get codes.
Idle sucks or hunt.
motor will start & run but once it get over 170 degrees it will not restart until cool.. you have now burned up trace in the computer ..need to replace or repair..
