hi mate, i think around 92-93 there was a change in the wiring but this is how i ve wired mine up and its a 94
PIN 30 = fused live from the battery
PIN 87 = to the spots
PIN 85 = headlight main beam wire ( on the multi plug, cant remember wich one it is exacly but its one of them)
PIN 86 = earth feed on the headlight multi-plug
theres a slight difference in the wiring on earlier mk2's apparently and to make the spots come on when you flash it has to go to the headlight earth wire because if you just run it to a normal earth on the chassis they will only come on with main beam after you flick them on and not when you flash aswell...... :? did that make any sense?
however, on the 4 middle ones on the roof, ( the two outside ones on the roof are wired up as above) ive run the wire off pin 85 into the cab to a switch------then from the switch in the cab to the headlight main beam wire on the multiplug.
if that didnt make any sense let me know and ill try find a diagram from somewhere.
AND try
www.pajerouk.co.uk because im sure thats where i got the info to wire mine up and theres plenty on there to go on.
