That's right, they won't, the numbers on the ECM,s have to match. If you attempt to hook it up you could fry the ECM as well as some of the other control componets.


they actually should interchange - verify the part numbers and ID numbers off each one first, if they are the same they can be swapped.

You have everything the same, engine and trany. The one thing you have to know is how many teeth are on the ring tone for the crank sensor. That has to match what the ECU reads. During those years they had a 16 tooth ring tone and a 32 tooth ring tone. The ring tone is inside the engine on the crankshaft. Only way to change it would be to pull the engine and take the crankshaft out. Easier to find the right ECU and wiring harness.
