could be like the 89-91.5 i think and only have a little black box called the "Air/heater controller" mounted under the steering post on the fire wall. or well thats where mine sits. i got rid of that whole PCM in the 92 when i put the 90's engine in it. i just used the 90's harness. so if anyone needs a PCM for a 1992 W250 5 speed let me know lol its just sitting under the fender taking up space. i dont know if its good or not. the 92 didnt have an engine when i bought it. i was thinking of using it for shotgun target practice but i decided that wouldnt be good since parts are kinda hard to come by for these trucks
