G'day Billy,
Apologies - I wired mine 15 years ago, and made a great wiring diagram. It then got a bath in rainwater, and is now illegible

. My harness is packed up in a box and I would need to unpick it to see how I connected it to the Torana wiring (I can do that if needs be, but it will take time).
There are six wires coming out of the column in a flat ribbon:
a) yellow - I didn't use.
b) light green - I didn't use.
c) purple - used as power ex flasher can
d) dark green - I didn't use.
e) blue - used as rh turn signal
f) light blue - used as lh turn signal
g) black - used as earth.
Cheers,
Harv
