:o Ive miss placed my <Bible> Cough. I mean my IS200 eletrical wiring book. Plus I dont own one for the RS model. So my problem goes... Does anybody know which wires to which I need to join a factory IS200 haeadunit into a Rs200 model? As the 2 headunits have different plugs. Aswell as this does anyone have the plugs out of the back of a IS200 model as the Audio instaler "Lost" one of these plugs when instaling the IS aftermarker HU... :angry: ANy solution would be much appreiacted. :)

I suspect that the problem will be that not all RS200s had the system with the separate amp, which could be why the plugs are different. I know mine didn't, and all I had to do to fit an aftermarket HU was to get the Loom adapter for a Toyota

That would be the smart way, Just fiting an aftermarket unit. However the unit out of my IS is basically brand new due to insurance so would be a waste to throw out, so really wanna try and fit it into the RS. I dont mind chopping the plugs at each end. Just need to know which wires to miss out and which to join.

This may be of some help to you http://z4.invisionfree.com/lexusaltezzaclu...wtopic=8256&hl=
