HI DOES ANY ONE KNOW HOW TO COVERT A 1970 NON RALLYE DASH HARNESS INTO A RALLEY DASH HARNESS?

yes i have ,most of the plugs exist in the harness,you will have to get a service manuel for the correct wires, plugs etc.,its not that hard,im sure dave might have the under dash schematic, if not like i said look for the service manuel.

How complete a job are you looking to do? For example, I converted mine, but I did not hook up the oil pressure gage or the clock. I didn't want to burn out the clock as is common, and I had a separate oil pressure gage I put in.

These two items and the tach are the only items that you will need additional harness pieces for. Everything else is there, but you might have to pull the harness apart a bit to get the length of wire needed. My turn signal light wires were way too short to reach the rallye dash as they were in the harness.

It is a simple matter to modify the existing wiring.
