I believe that you can make a standard wire harness work with RA manifolds, but if you're buying a new harness, buy the one for RA manifolds (RAIII/RAIV).
The standard engine harness has the starter wires cut and wrapped to route through a tube mounted to the cylinder head in front of the rear most exhaust port on the drivers side;
The RA harness has the starter wires cut and wrapped to run down along the front of the engine, along the oil pan lip to the starter solenoid.
When I rebuilt my harness (used donor original 1970 f/s Pontiac harness) I modified it to route properly (the engine/starter wiring was a mess that I inherited when I got my car).
