Just an update and further help needed please , fog lights are working great , all sealed with heat shrink , all done properly with relay and fuses . I am now wanting to put in a reverse light , I have fitted light on rear and earthed it via rear lights , I have piggy backed a wire from the rear of the new fog light switch (permanently live ) to back of Landy ( all very loose , nothing set in stone at moment ) and switched it on and rear light lights up so that's all good , I'm going to wire it like this now I know power is getting to it ........ Lamp to earth in rear lights , lamp to wire to front of cab and to a new switch and then that switch will piggy back to permanent live from the original switch , will this work ?? is this safe ???. Obviously the reverse light will only be on for 60 seconds at a time , is another fuse required somewhere here and if so where please ?? Thanks in advance
