There is no write-up for the swap. You are doing custom work with steps that are specific to various models. Assuming the ECU is for the 98 model year, you need a harness that matches the ECU. I think 98-00 models will work, but don't quote me on that. You need the harness that also matches with your engine and transmission combo.
The dash cluster will be interesting if your 96 model has a speedo cable. The 98 harness and dash cluster is electronic speedo, so you'll have to convert the speed sensor.
