if you have a multimeter put it over the plug see what the voltage is ,or stick a bulb over the plug....
there are 2 fuses E134 & E026 both in the left hand fuse panel and behind the dash there is a relay for the radio ..there should be 2 plugs GREY for POWER & BROWN for SPEAKERS... PINS 4 & 7 should be you 2 feeds power and ignition..wire numbered 1143 &1108..or depending on chassis number they may be 1143 and i think 1153 &pin 8 should be an earth
