408 : How to route a new wire from battery compartment to boot?

[DODD]

Hi David,
I am actually in the process of doing the same thing. I intend to have a fuel pump isolation switch on the dash board, not as an anti theft device, although it may help a little. My real reason for the cut off switch is because a few years ago I had the unfortunate experience in one of my other cars, a V12 Jaguar, where the accelerator jammed at full throttle on acceleration. It’s surprising how quick these cars reach 90 mph in such a short time, fortunately all ended well.
Anyway, back to the point; I have taken a new live wire via a newly installed fused distribution board (and relay) in the battery compartment, from there my wire goes behind the dashboard to the switch position, before dropping down to the prop shaft tunnel below the carpet, the cable runs to and through the cross member supporting the rear seat base and then below the rear seat and into the compartment behind the steel plate in front of the petrol tank (the steel plate is directly behind the back of the rear seat), once there it’s a straight forward job to push the cable into the boot area in the vicinity of the fuel pump.
I suppose there are easier routes but as I have my back seat out, I have chosen this way.
Additionally, I have also added a few additional wires as a spare should I ever need it for something else.
Hope this helps.
Regards
Brian
