Fitting a stereo into a mkIII golf

[salvadorescobar]

Hi,

I have just bought a new stereo to fit into my mkIII golf and am having a little trouble. Hopefully someone can help.

At the golf end I have 2 connection blocks that fit into the standard ISO fitting. At the stereo end I have an ISO fitting.

In the installation manual there is a part that shows the following connections :

Yellow - backup (or accessory) connects to Yellow - To terminal always supplied with power regardless of ignition switch position.

Red - Accessory (or backup) connects to Red - To electric terminal controlled by ignition switch.

But the installation notes that for some models of car this will need switching (ie. Yellow to Red).

Can anyone tell me how I can find out about this? I don't think I can do any harm if I don't switch them and they need switching. All that'd happen is that I'd get no power, or I'd alway get power. Right?

Any help would be appreciated.

Cheers, salvadorEscobar.

Get out a multimeter mate, one will be a constant 12V one will be switched.

IIRC the constant 12V is for the memory of the stereo so you dont use all your channels, and the 12V switched is so that the stereo comes on and off when you turn the ignition..

You can see on the stereo which wire needs +12V and switched 12V and change them accordingly

If you aint got a multimeter,

First test:
Just fixup the stereo player (without your keys in the ignition) and if your stereo backlights light up, you need to swap the wires.

Second test:
Fix up the stereo and turn the ignition key one click (the A/C position)
If you tune a radio stations in say Invictor of radio 1 etc, store it in memory button 1. Now turn your ig key OFF to the remove position for a few seconds and then turn it back to the A/C position. Your radio station you stored in memory button 1 should still be remembered.
