Hi Guys! I have bought a 2002 Polo with no speakers fitted in the rear doors. Looks like there has been some fitted in the past tho. Trouble is I can't find any wires for them? There are two sockets which plug into a socket in the door pillar, but these all seem to go up to the locking mechanism in the rear door. Should there be a third plug for the speaker ,or do the wires come from somewhere else? What colours are they? Would much appreciate a hand!

There should be a 4 pin plug with (left Brown/White & Blue/White)  (right Brown/Blue & Blue )  wires

Ok thank you. Looks like previous numbly has done away with everything! At least now I know what colour combo wires I need to find! Now where is that torch..........
