Throttle cable instilation

[Leroy58]

I have a Triumph Bonneville T140V 1978. I am trying to install new throttle cables but I am unsure of the path to take.
I have looked on the internet to see the correct route and I have found 4 different paths.
1. Over the headlight bracket then into the frame.
2. Under the headlight bracket then into the frame
3. Through the headlight bracket then into the frame
4. Straight from the hand piece into the frame

Can anyone tell me the correct path??

Thanks Leroy

I don't know it there is a correct way but most I seem to remember had it going under the headlight bracket. GrandPaul should be along before too long, I'm sure it there is a correct way, he will know it.
