What do you mean, wont take?
Which part isnt working mate??
is it even powering up?
The rsm shud power up just using the red 12v ingnition, and black earth..
If the rsm isnt powering up with just them 2 wires they are more then likely faulty.
As for the fcd, can u disconect that entierly to and see will the car run right?
yup definetly wired wrong.
Get a 12v fused from behind the radio, and earth.
Then there is a wire diagram that comes with the rsm that shows the pins that you tap into ,for delimite and rev clock.
Its pretty easy to wire on the gt starlets.
as for the fcd im not to familar with them so some1 will have to shed light on it.
But from the sounds it could be wired wrong or set wrong.
