If you replace your main harness now I believe you would only need to get the conversion EFI-MAF 5.0 harness later and blend it into your system. Certain things would drop off from the old harness and some new EFI harness wiring would need to be grafted in but it is not that bad if you have decent wiring skills. You do wind up with some cut off wiring unless you strip the jackets off everything, pull the old wires completely out and put new tape or wiring loom over the converted wiring system.
