Is there a way through the engine bulkhead for a cable without drilling a hole

 

IIRC, this was asked not long ago. Scroll down a few pages and you may find your answer.

However, I'd expect there to be some room in the cabin/engine gromit to feed a few wires through, if that is what you desire.

HTH

 

Thanks !!!! Difficult but I found it

 

I did it, not too tricky once you find the hole!

 

I could rise to that comment but I will resist!!!
