You don't need a different harness if you make a couple of mods to the existing one. You'll need to run a wire from the "-" side of the coil to the tach for it's signal. You'll need to run a wire from a switched power source for the tach power. Run a wire from a constant power source for the clock. Then last but not least, you'll need a different oil pressure sending unit for the oil pressure gauge.

Super easy.

Ya, keep the original harness.  Bill and Rose Evans do make a little tach wire harness add-on. 

Change the sending unit (oil) from idiot light to gauge

Just a few screws and the old stuff comes out.  Just got to drop the column some.

70-71 gauges run usually between $350 (rebuildable cores) to $2k (fully rebuilt).

Not hard at all!

I also might add, the heater panel and 70-71 gauges make this a costly swap. The Rally gauge light bar can bring $200 on E-Bay.
