new s13 iacv harness plugs different than old iacv?

[Rally240sx.com]

I bought a new iacv from a Nissan dealer for my 91 ka24de turns out the "new" plugs on the iacv are different from the old iacv plugs and dont match the 20 year old harness. Nissan told me they changed there plug design since the cars were built and I either need a new "harness" or just cut and splice the wires onto the new iacv

just wondered if anyone else has found this problem and what you did about it?

Thanks,
