I curious as to what year Dodge started using VTSS in Ram trucks and how if any can tell if it has it? Also what year did they start using the SKIM system instead?

98.5 was VTSS
SKIM wasn't used until the 3rd gens

So did all Rams after 98.5 have VTSS?

No sir only the ones with the factory alarm?

Okay thanks for the help. If you're looking at one in a JY how can you tell? And I'd guess that there isn't any way to know if you are buying a used PCM online?

Im not a Jeep guy so I can't say. Usually there is a light or something, somewhere. It flashes when the alarm is engaged. A used pcm online, yeah no way to tell

JY is junk yard not anything to do with Jeeps. The square headlight Wranglers are a YJ and the Wranglers like I have are a TJ and the newer Wranglers are a JK if 2 doors and a JKU if they are a 4 door. The newest Wranglers are a JL or a JLU and the new pickup in 4 door version is a JT. Is that enough Jeep info for the next 10 years?

I always wondered what those 2 letters meant. What about WJ and that?

A WJ is a 99-04 Grand Cherokee, 93-98 GC is a ZJ and the popular Cherokee is a XJ. http://www.fourwheeler.com/project-v...ur-jeeps-code/

So complicated :b I like the Rams name (2nd Gen, 3rd Gen, etc)
