Anyone know if there is any difference between a 1970 and 1972 Wiring Harness, Non A/C. I noticed that one of the pinouts from my used harness is blanked out. This may impact the interface to the instrument cluster. Any insight would be helpful. Thanks.

A suggestion: Look at www.wiringharness.com (M&H Electrical Fabricators) and check out their on-line catalog. If the part number is the same, so is the harness.
