Just to note,
I didn't pick the fuses there Vicky Greens.
I moved the wiper because its not safe to go bigger than 20A on the lights as they are wired in series and the fuse may not blow due to wire size restricting current flow which means heat and fire. With headlamps on about 7amps is pulled with one fog fitted add 2amps, reverse 2 amps, brakes 3.5amps. So we have a total of 14.5amps. And if you flash main beam thats another 7.5 amps, indicating thats about 2amps.
Peak current could be 23amps, with a wiper going that means fuse blow to me.
As the wiper and heater are wired in parallel off the second 20amp and the length is fairly short it would be possible to increase the fuse if neccessary. I have ran them together and they dont blow the fuse, but I will check the current draw more carefully before finishing the wiring.
