Ok still need help

Right we have had ago tracing the wires ect Cant find a YELLOW wire @ the switch end But have @ the fuse box end That runs into the head light fuses and the white relay that acts as a voltage dropper

Right well we have found that the head lights are running @ 6v on dipped Beam But this does'nt alter when the ign is on we have played around by bypassing the (white) relay and have 12v @ 1 headlight But still no Full Beam

Have still to try the storks it was bloody tight doing it in the garage in the dark with only touches
