Remote Truck Release - '69 Barracuda Convertible????

Was there ever an option for a remote (electric) trunk release mechanism in a 1969 Barracuda Convertible? The one I'm restoring has an electric release latch but the OEM wiring harness (Year One) reproduction does not have a provision for this option. If Plymouth made that as an option, where would the switch go on the dash?

My guess is my buddy who started the restoration of this car put this in from a newer Mopar car.

Thoughts????
