OTC 4000e vs 2000 cartrages the same?
 

Hello all.
I want to help my brother with his 86 C4. I have a OTC monitor 2000 scanner but not the right software cart. They where lost with time.
I also have a 91 Dodge I would like to use this scanner with.

I see the "pathfinder II" cart's for cheap on Ebay but they don't say if they are for the 2000 or 4000e. Do these 2 scanners use the same cartridges or are they specific to the scanner?

IMO pathfinder II is 4000. Monitor 2000 had a "3 in 1" cartridge although 95% of the time I used a GM specific cartridge. A friend had a 2000 with a 3 in 1.
