Default ECU Confusion

So I’ve been conducting an auto to manual swap on my 94xj and everything is going great until now. I ordered the part from Quadratec since I live on a island in the middle of an ocean. They said it was for 94-96 so I’m a little lost. I’ve was replacing the auto ECU with a Manual ECU. Got the new ECU and bam neither one look alike. I’ve read all the forums possible and everyone says you switch them out. So what is gods name am I missing. Cause this does not fit.

They sent you the wrong ECU. The one on the left looks like a 1999+ ECU. Is there a part number on it?

Yeah looking at it now I should have double checked. I am very new to jeeps so this is a whole new learning curve for me. I see that finding one is going to a wonderful process. Are there any substitutes such as using a YJ ECU. Or does it have to be a XJ ECU. Which part number are you asking for the new or old ECU?

'96 is OBD2, the one with 3 connectors

'94 is OBD1

download the "94-96 Factory Parts manual and enter the part number you want into Google
