I just did the same with my 96. The donor was a 96 explorer with a 4.0. I pinned out each connector on paper and all were the same, plug and play. Tach works perfectly with my 2.3. I verified the tach with PCMScan. I changed the speedo out to keep the mileage. All other guages and lights work with the same sensitivity as the original cluster. Speedo is off by 13% due to the rear suspension change but a new gear will fix that next week.
