Help With Fitting Cd Player

[billy wizz]

I am trying to exchange the radio /cassette unit for the original unit which has a radio /cassette /cd player, all original Toyota equipment . My car is a Yaris 1.3 GLS automatic X reg. 2000. I understand that you need a split wire - part no. a v c - l a n 08695-00260 cannot find one anywhere. Can anyone help me with this. I rang Toyota parts and was told it was discontinued. Is there an alternative. I want to keep the car looking original if I can.

Thanks for any information

Phil.
