great information fella's il take it on board,

question i have Maddat fuel/serge setup tucked up under the tray behind the passengers seat, locating the battery there in the tray,

now with the cable how far from the fuel system must it be? and where do you poke the cable through, can the negative cable be earth somewhere in the tray!, i just want to do this right

Cheers for your help

It is best to run a negative cable to the engine block as stock setup.

Add a second battery-to-body or engine-to-body wire. You can ground the fuel pump via the body but it must be an unpainted connection.
