I don't have a TR4 wire harness diagram handy but assuming the wire colours are consistent (a safe assumption in this case) the Green/Brown wire is for the reverse lamps on the TR6 so most likely, yes.  One of the green wires and the green/brown wire connect to the reverse switch on the transmission.  I am not sure what the other two green wires are for but perhaps the heater and the signal flasher.

I am putting an early TR4 together and am in the process of wiring the car.  Just above the hoses coming into the heater and adjacent to the main center cluster, there are 4 wires coming off the harness:  three greens spliced together and a green/brown.


Green/brown can be kinda ubiquitous, so I am not sure what it is for.  A back-up light maybe?


If anyone knows what these wires are for, can they let me know?  Thanks!
