How can I run a wire inside from battery of Xantia?

All your wiring,and many other things run through the bulkhead,in the engine compartment locate the wiring harness where it goes through bulkhead,peel back the rubber grommet push a stiff wire through(copper earth lead)with an eyelet formed on the end,and have someone locate it on the inside and pull it through with your wire tied/taped to the end(your end) it's fiddly but it is the way it's done.
