difference between 1972-1973 Cuda rear wiring harness?

Anyone know the difference between the Cuda 1972 and 1973 Rear wiring harness?

I don't but there are factory service manuals under resources you could compare the wiring diagrams

1973 likely has extra wiring for the seat belt warning system. As for taillight function, they will both be the same.

I printed off wiring diagram for 72 and 74. The only difference I can see is 2 courtesy lights on the 72 rear harness. Where would they go and for what car/option (rear panels of Sail panel would be my guess)?

The only E Bodies with 2 "courtesy" lights are convertibles

That makes total sense. So I my swell use the 74 harness(New) I have rather than purchase a 72 harness. Thanks
