jim i took amp readings and are with nothing switched on red wire 4 amps red and blue wire 0 amp red wire that seems to be in a seperate loom 0 amp and now with every thing switched on red wire 19 amps and 29 amps when rad fans kick in red and blue wire 31 amps and red wire in loom of its own 26 amps and my fuel pump is on a circuit of its own that pulls 7 amps on tick over so you will have that load on one of the cables i think the red wire that seems to be in a different loom is for heated screens the black tails on my loom got verry hot so looks like i will be changeing them but think 40 amp fuses may be advised
cheers alan
