are there any major diferences between the 70 and 72 rallye harnesses?

for the challenger....rallye guages .....are there any major diferences between the 70 and 72 rallye harnesses?

I don't think there is any difference at all. I had 72 gauges in my 70 for a time.  Physically the gauges are different, but the same wiring.

Are there any issues with a seat belt warning light or something on the '72-'74 Rally dashes?  I dunno since my car has a '71 style in it.   

Like MEK said, physically they are the same but the difference visually is the placement of the reset knobs and the earlier '70 + '71 Rally dashes have an 8k tach, where as the later ones had a 7k tach.  I wonder what the difference in the tach makes with the wiring?

I would need 1 of each year manual to check wiring positions , I don`t have both amnuals though

biggest differences between 1970 and 1972 wiring harnesses is teh location and type of horn relay.  Other than that, they are identical.
hope this helps,
