The tc in my 93 went bad. Picked one up from a guy who had one in a 93 also, his has SYE installed and a tom woods DS. Pull mine out today and it has a wiring plug that the new one doesn't. The exploded view of the np231 in the Haynes says its a vaccum switch. How did this guy get away without running it? Can I get away without running it? any help is appreciated, thanks.

 

Pics?
A 93 shouldnt have any kind of vacuum at tcase, AFAIK... Just a 2 prong switch for the light.

 

Im posting from my phone, cant post pics. The one im talking about is on top of the tcase housing near where the linkage connects.

 

It is 2 prong, but the Haynes manual called it a vaccum switch? Your saying its for the light on the dash that displays "4 lo" ect?

 

Well, Haynes is wrong, as usual...
This plug?

 

Thats the one! Wonder if it will throw a cel if its not connected? I really dont need the dash lights...

 

Itll be fine, Ive had 2 jeeps (89, 97) and my girlfriends 96 that they didnt work in.
Im just wondering what the difference is... I didnt think the plug changed.

 

Yeah this replacement tcase doesnt even have any other connector besides the one for the speedo. And i have no clue as to what year it came out of, the PO said it was in his 93... Anyways, thanks for your help!
