ny new toy still has the original ford 2000 stereo in it.

it has the tape head unit, and a slave cd player but when i removed them, there are no speaker wires running to either?

theres a cable connecting them (blue) and one that runs from the headunit to behind the dash (red)

both have thier own power supply connectors

any suggestions how to fit my own cd player and use the original speakers etc

cheers
