Multichanger

Hi everyone, this is my first post so hope everyone is fine.

I used to have a R reg 1.4 Bravo but it got wrote off by a Vitara, anyway just bought a W reg 1.2 Bravo and i am trying to locate the wiring for the multichanger, in my 1.4 it was in the boot, but i cannot seem to find it on the 1.2 can anyone help with this, like is it located in different place or do i have to buy complete wiring from main system

im not sure wer the wiring is in the bravo, generally if it had the option then the wire is readily accessible, sometimes its quite small behind the glovebox of something and requires an extension lead but fiat will charge a ridiculous amount of money for this lead so your best bet is to get to you old car a break it a wee bit more and take the lead from it. also make sure your headunit can take a multichangers, even though units may look the same they come with different abilities and accessories, as soon as you take the stereo out you will see if it has the extra plug for a changer

my cd changer wiring was on left side of car and going underneath passenger carpet
