Can any one tell me if the lead that connects the head unit to the cd changer is a std pioneer p series connector or a lexus special connection. I ask this as i am thinking about changing the cd changer to a 12 disc set up and mounting under the rear shelf. the head unit says that it is a pioneer head unit.

it is a lexus special on a mk3 i would of thought it would be the same on a mk2

It is a special loom.

Ok that scuppers that plan then, is there an adaptor cable available to link the head unit to a different type of changer. anyone else up graded the changer but retained the original head. and how did you do it????????

dont think so not sort of thing you see done very often

If you are planning on using a pioneer 12 disc changer and you have the required electronic skills you may be able to adapt the unit to work.
If I remember correctly Pioneer uses data lines (rx/tx) to control the changer from the head unit.
I have the service data for the 6 disc boot changer if this will help but it is to big to email.
Why are you replacing the standard 6 disc unit is it faulty?
Might be worth a look on ebay for a working unit which would be a straight swap.

i believe the stereo is designed especially for the LS400. i dont think the oem head unit will work with another changer..but try on clublexus.com for a better answer..lots more LS owners on there...
