M42 engine into m44 car
 

I have read the swap forums and still cannot figure this out . I have a 96 318ti with the m44 obd2 setup . My engine head is cracked and losing water . A friend has a m42 obd engine complete with qoring harnesses and everything else possibly needed to do the swap for cheap . When I swap the entire motor do I use my old qoring harness or just plug in the new harness ? Or do I need to get the computer from his car too for this swap to work ??? Please help thank u !!

Here is the info you need. I will be doing the same eventually
