The remote wire needs to go the ISO connector
on the back of the stereo.
To get to the stereo you need to remove the front of the centre
console. There are 2 screws at the bottom of the unit, Undo
these and unclip the front of the centre console.
NB : There is a ribbon cable that connects to the front
panel - unclip this!
Once the front panel is off unscrew the four retaining screws
and pull the stereo unit forward. Unclip the wires at the
rear and remove the unit.
The remote wire needs to go to pin 3 shown in this picture.
You can tell which one it is as it is the third wire from
the edge and is the black wire. The best way to tap into this
wire is to cut the wire and then crimp both ends back together
with your remote to the amps.
