MK2B STEREO WIRING HELP
s and b
30-12-2012
There is only one full time live in a mk2b punto at the stereo loom and its constantly live so even with key in your pocket its still pumping volts, ie your radio runs the risk of flattening the battery over a period of car non use or worse some car stereos get very hot if left with permanent live

That I believe is the standard ISO fit wiring

Coloured blocks might be for the CD changer under back seat.. or Amp -or Sub..in the boot

Thanks, I knew the iso, just didn't know the coloured blocks, even asked a guy at the fiat garage haha. Could it have had the speaker upgrade package at one time? I'll have a play on Wednesday when the speakers and stereo get here, paid more for that than the car.

Re: MK2B STEREO WIRING HELP

Can someone confirm if this is what I essentially have to do:

I locate the constant 12v power lead ( which i presume is the red and black wire, not sure if anyone else's is but previously when attempting to work on central locking I identified this red and black wire to be constantly live) which essentially, I should find the constant power lead where the cig lighter is?

and I expose the copper wiring and connect (solder) an additional wire to the yellow wire (whichever unswitched lead colour it is, which can someone just clarify what it's meant by unswitched aftermarket stereo lead? )

So to simple it down, find constant power, which is the cig lighter. Get extra wire (black as used above) connect said black wire from the constant 12v lighter wire to the yellow wire (which is the unswitched lead?


Also say if I'm trying to do it to a port like this



And the wiring they provide is this


Is everything described here still the same process? Except for I would need a cable like this right?
