All my 94 Z28's cluster gauges except the speedo and gas stopped working after motor swap?

Question

The tach, temperature gauge, voltage gauge... all that stuff stopped working after my mechanic swapped motors and he didn't bother to fix it. The speedometer and gas gauge are working, but everything else doesn't do anything. The CES light, coolant temperature monitor lights etc... all the lights work fine. Any ideas?
