The engine harness is basically the same for both years. The big block harness has a longer oil pressure wire and the TCS wiring is different. Another concern is the heater blower wire, if the harness is from an A/C car and you don't have A/C the blower wire will be short because the end would have been cut off during assembly.
Interchangability of engine wiring harnesses?
If I were to get a used engine wiring harness from a 71 with a BB and manual trans., could I still get this to work with my 70 with a smallblock and an auto? I am OK with subtle differences, and I will not be wiring in factory gauges.
I know they have slightly different part numbers from the repoppers but if I have a loose wire or two or need to add in a wire somewhere its not that big of a deal considering I will have saved a bunch of $$.
