AW4 NSS compatibility Q

[Rockfrog]

So going over part numbers from Rockauto and such ...

 

It looks as the NSS has never really changed other than the plug end. In some cases the part number is the same between a 1990 AW4 NSS and the 2000 AW4 NSS in my XJ ....

 

Is this correct? I know a number of parts were only updated for reliability and are fully backwards compatible (shift solenoids being one). But is this true or a typo on their parts .... I just so happen to have a 1990 NSS and was thinking of cleaning it for use as a spare if this were the case?

The parts manual shows the 91-96 NSS all the same, then the p/n changed for the 97-01 XJs. Probably the connector as you stated.

I'll take some snap screen pictures of the thread so no one has to go hunting for it .

Forgive my ignorance, but... NSS?

[gogmorgo]

Neutral safety switch. Only applies to automatic-equipped models. It tells the trans computer which gear you've selected, and prevents starting in any gear other than park or neutral.

Oh gotcha yeah I'm familiar with a neutral safety switch I was totally in the dark with the acronym hahah.

thanks!
