All is well now. I swapped the old harness to the new engine. Everything is running great. I had to plug one of the vacuum ports on the back of the intake manifold.

By the way, the electronic speedo from the mystique works perfectly using the VSS from a 96 model.

Thanks to everyone that point out the wiring harness problem.
