91 Si engine harness into 89 DX question

Rather than modify my DX harness for MPFI, can I just plug a 91 Si MPFI engine harness in? Or would I have to put an Si in-car harness in as well?

Help, please?

It will be much easier to modify your DX harness than it would be to replace it with a Si harness. For MPFI, you only need to add like 4 wires or so.

Well that's up to you, but you are going to encounter more headaches trying to put an Si harness in than you would just adding the wires that you need for MPFI.
