I've just come to fit my new stereo in my '99 Spider. Having removed it and plugging the iso connectors . . . .Nothing, not even a glimmer on the radio.
when I look at the car power iso plug it only has 3 wires Red(left top), Black(Left Bottom) and a thin blue/green wire(second in from top left).
On the radio Plug there are 5 wires on the connector.
When looking at the radio car wiring harness I can see two wires not connected, one yellow and one orange (i think).
The speaker wiring and connector looks fine.
Can anyone offer advice as to which wires (and colours) should be in the Power supply part of the iso and what order.
