1970 Fiat spider flasher wiring help

[edsfiat]

I am in the process of restoring a 1970 fiat spider. I have 2 wiring questions if anyone can help.

1) 6 prong emergency flasher On/off switch

Terminals:
H
L
I
V
D
T
Wires:
double white
red
yellow/black
grey
white black
I believe double white to V, Red to H, yellow/black to I
not sure where grey and white/black goes

2) 3 wires go into the transmission tunnel on the passenger side. 2 go to the reverse switch, there is also a grey maybe black is it a ground.

Thanks
Ed
