Re: Odometer question
Well It depends. Older YJ's and CJ's used a mechanical Speedo; and all speedo cables, regardless of make, that I have seen are the same. So If you have a stock Mechanical speedo and a mechanical speedo output on the NP247 then a stock cable should work.
However, sometime around 95 Jeep went to a electronic speedometer and sender. My 95 is Electronic, but it may have been a mid year change so check yours. If you have an electronic speedo but no stock sending unit then I don't know what you need to do, also stock it may have needed a Computer to work. To complicate maters farther, your NP247 may not have a mechanical speedo output. You did not say what year or vehicle the Transfercase is from, (not that I would know what output it has but others might). If it does have an electronic output it still may not be compatable with the jeep speedo, but may still be needed for your engine's computer.
You will need to find out the Fallowing.
1. Is your Speedometer Electronic or Mechanical? To do this you will need to crawl under the dash and look at the back of the speedo for a cable or where the cable would attach.
2. Does your transfercase have mechanical or electrical speedo conection or both? If electric, is the current engine computer conected to it?
The solution to this will likley no be that hard but there are many posible compinations of parts invalved, and to propose a solution for every posability only to have one be right is not practical, so we need to know what you have. Also, There is no substitute for doing your own reseach. Try to findout what others did, Google is your friend.
