the brown wire is from battery so that should give power but check your main relay because I think that activates the fp relay and the blue red wire goes to fp where it grounds through that. this is form an xj6 as I don't know what model you have. wite brown wire is from main relay and pink/brown wire goes to ecu which probably turns it on
