Do you have a speedometer cable? I thought '94 was the first year they went all electronic.

It is in the extension housing of the transfer case... which is the part of the case inbetween the back case half and tailhousing. If you are looking from the back of the transfer case while it is in the truck, I would say its about at the 10-11 oclock position.

 

I think I found it. Is it a two prong plug or could there be a variety? I have pulled the plug on what I think is it and it appears to have two prongs on it. Great pictures!! Thanks very much.
