It won't work. Your gonna need to repin the harness. Takes an hour or so. I just did the same thing.I think 17 or so different pins.

Is there any downside to using the 98 harness? What Im trying to do is put an ls1 in my 93 formula and I want to change the interior harness, So I don't have to change the harnesses all around and run the possibility of gauges not working the way they are supposed to. I plan on changing the gauge cluster out to match the newer harness
