to find it follow the red heavy lead from the battery
(note hope you have the code to the radio )
BEFORE you start anything disconnect both the battery terminals
to remove motor undo (what ever type of nut fitting and wire connection that is holding motor in position).
refitting should just the reverse, bolt up motor, refit wires on reconnect battery terminals. try the starter and lastly reprogram the radio code
