My ECU/ECM died (supposedly. It's the last thing the test said it could be, and the rest aren't it...). However, I have had difficulty finding an ecm- And now, I think I have. However, the part number from my computer is 56028 289, whereas the computer I found is 56027 380. However, my jeep is a 94 wrangler, 2.5L, manual transmission..and this is exactly what the new computer says it is for. Anyone know if they are compatible? I asked the seller too, but maybe I can get a quicker and more knowledgable response here.
