Alpine CDA-9831 into 2002 Toyota Celica GTS

I had this head unit(Alpine CDA-9831) in my 1991 Celica, it was basically plug and play, but im confused on how to install this into my new Celica. I bought a wire-harness from best buy (Metra 70-1761 kit) and their saying i have to cut the alpines harnesses end off and splice this kits wires onto it, so it connects to the OEM pre-exsisting end, but my alpine 9831 has more wires i believe, so im little confused and i don't want to cut my head units wires unless i have too. please help. this car has the 8 speaker setup, not sure if that affects anything or not.

SOURCE: Need pinout for Alpine CDA-7940 head unit

facing the back of the 7940 the top left corner is pin 16 the top right corner is pin 9. The bottom left is pin 8 and the bottom right is pin 1. Only a few of the 16 pins are used due to this unit only having pre-outs, no internal amplifier on this unit. Pin 1 red (ignition), Pin 2 pink/black (interrupt), Pin 3 orange (Illumination), Pin 8 black (ground), Pin 9 blue (power antenna), Pin 10 blue/white (remote turn on), Pin 16 yellow (battery).

Trying to play Ipod through my Alpine cda-9811

you need to set up your system to accept aux. this means you will need to set the 'aux on', as the default setting is 'off'. use the manual and refer to page 23 & 24. please read the instructions carefully, as they are slightly confusing.

Alpine CDA-9884 poor FM recep.

Check the adapter you hooked up to the stock stereo cable and see if its loose or try a new one to see if the old one does not work. Or it could be that your antenna cable that runs to the outside its all f'ed up.

Alpine Ipod/Stereo Error 1 message

my alpine cda 9856 only displays that message when my ipod dies. so your ipod pobably dies then the head unit recharges it enough in the time your resetting it that it can play again. :)
