There are two batteries on a modern XJ8. One is in the trunk area.
To jumpstart a Jaguar XJ6, first ensure both vehicles are turned off. Connect the positive (red) jumper cable to the positive terminal of the dead battery and the other end to the positive terminal of the working battery. Then, connect the negative (black) jumper cable to the negative terminal of the working battery and attach the other end to a grounded metal point on the Jaguar, avoiding the negative terminal of the dead battery. Start the working vehicle, let it run for a few minutes, then attempt to start the Jaguar.
The battery is under the saddle. The red cable goes to the terminal marked positive (+) and the black cable goes to the terminal marked negative (-).
To jump-start a Jaguar XF, first ensure both vehicles are turned off. Connect the positive (red) jumper cable to the positive terminal of the dead battery, then attach the other end to the positive terminal of the donor vehicle. Next, connect the negative (black) cable to the donor vehicle's negative terminal and attach the other end to a metal ground on the Jaguar, away from the battery. Start the donor vehicle, let it run for a few minutes, then attempt to start the Jaguar XF.
To jump-start a 1998 Jaguar Vanden Plas, first ensure both vehicles are turned off. Connect the positive (red) jumper cable to the dead battery's positive terminal, then attach the other end to the positive terminal of the working battery. Next, connect the negative (black) jumper cable to the working battery's negative terminal, and attach the other end to a metal ground on the Jaguar, away from the battery. Start the working vehicle, let it run for a few minutes, then attempt to start the Jaguar.
To jump start a 2003 Dodge Intrepid, first ensure both vehicles are in park with their engines off. Connect the red positive (+) jumper cable to the dead battery's positive terminal, then attach the other end to the booster vehicle's positive terminal. Next, connect the black negative (-) cable to the booster vehicle's negative terminal and attach the other end to an unpainted metal surface or a grounding point on the Intrepid. Start the booster vehicle, let it run for a few minutes, then attempt to start the Intrepid.
To replace the positive battery cable on a 1996 Ford Aspire, first disconnect the negative battery terminal to ensure safety.

Red, positive + cable to Positive + battery terminal. Black, negative - cable to Negative - battery terminal.
It is usually red.
To change the positive battery cable on a 2001 Toyota Sequoia, first, ensure the vehicle is turned off and the keys are removed. Disconnect the negative battery terminal to prevent any short circuits. Then, remove the bolt securing the positive battery cable to the battery terminal using a wrench, and lift the cable off. Finally, attach the new positive battery cable by securing it to the battery terminal with the bolt, and reconnect the negative terminal.
When connected to the cable which normally runs to the starter it completes the circuit. Electrons flow from the negative terminal to the positive terminal.
From battery to starter solenoid
