Thanks, XXXXX XXXXX I tell which fuse controls the trailer winch? The connector I have that fits the standard 7 pin trailer connection on the Jeep, has only has a 2 pin connector for the winch on the other end. If I had a readable diagram to locate the three fuses above I could remove them one at a time and check for voltage at the two pin connector. Where can I get a printed fuse box diagram?. Can I fit a 60 amp fuse in the fuse holder?

Under the lid of the TIPM should be a picture of all fuses and relays in it With the locations printed on it.
