HEI wiring harness.

Its time to order the engine wiring harness for my 72 Dart Swinger. I am planning on switching to a ready to run HEI distributor. I see Classic Industries has a Hei harness:

1972 All Makes All Models Parts | MA2271 | 1972 Mopar A-Body 340 With Hei - Engine Wiring Harness - Stock With Ecu | Classic Industries

Is this for the RTR distributor or is this for an stock electronic ignition module? Has anyone use this one? Or am I better off getting a points harness and bypassing the ballast resistor?
