Firewall Harness: Where does this go?

[Topcat]

And what is it for?

[Topcat]

maybe 4 speed reverse light?

Dash mounted reverse light for 71 up E Body. The large grommet exits right above the gas pedal...not sure if 70 is the same

Thanks.

Would that mean that these reverse hole locations (shown) aren't applicable for a 71' Cuda?
Or would they be the same?

Correct, 1970 was different

O.K. So I need to see a picture (if possible) where the right hole needs to be made.
If you have one, that would be great.

I don't know how to add fancy titles on my pictures, but this is my 1971 Challenger 4spd firewall. You can see the large hole just above the two gas pedal mounting holes. You should have a dimple there if it's a factory firewall. The hole measures 1"

Thank you very much!

on my -70 cuda,the reverse lamp hole is as in the pic of the red car above.under the reverse lamp hole is the hole for the road lamps.. so once again,the clutch safety switch hole is the same on barracudas and challengers...its NOT under the reverse light hole on barracudas or cudas or grand coupes.
