So a big screwdriver had to be pushed into the hole where the wires come through the bulkhead,
it needs plenty of swivelling about to make the hole big enough for the wire to pass through and even then it takes a very hard push to get it through, once through the hard parts over, just pull the wire out the other side:
And then its a case of using cable ties to get it over to the battery, i just used the big thick wire on the bulkhead to tie them onto:
When i got the wire into the battery box, i put on some hoop ends onto the wires and put them onto the two terminals:
And that's a good 12v feed in the car now. Ill be able to use it for the footwell lights but also anything else that i want to add inside the car without buggering up the BSI
