Dear ICE gurus,

There comes a time when a man needs to learn to install his own damn HU.
I bought a single din HU from 12.12 sales and got laughed at when brought to accessories to install , reason being no one in this era using single din anymore.

Long story short, decided to install it meself.

I've even bought a fascia and a single din storage to go with the player.

The issue I have at the moment :

1) which site can I get a OEM factory radio player wiring diagram for Vios (04), Grand Vitara (08)

2) I've been interested in buying a Nakamichi double din for Grand Vitara and it says it's plug and play. When I asked (online chat function) if the steering wheel control works and they say I need to get socket and antenna. Does the socket means harness?

Therefore, as you can see I have lots to learn. Been watching YT for HU installation and just need few more information to gain more confidence to proceed.

Again, appreciate any advice for this DIY attempt.

Thank you in advance.

Thank you, my kind Sir. However, don't I need to know the function of each wire? Ex: Black for ground, white for front left speaker, etc.

I found the harness online and even ask seller if they can tell me the assignment of each wire and seller is unable to provide such information.

In this case, do I need to use the testpen and AA battery to find out ?

The reason I posted in low yatt Vios forum hoping someone has the wiring diagram. First time doing electronic work, that's why so many questions.

Any further advice is much appreciated.

erm, cant show the socket as i yet to remove it but heres a pic of the stock radio.

Vios

Nicely written. Thank you.
I am finding every excuse not to do it myself and looking for anyone that want to mess this up together. Knowing myself, i_ll probably miss a step or two.

Thank you though. Much appreciated
