So I have purchased a set of Bonamici rearsets which will require replacing the 4 wire brake switch (one N/C contact) and (one N/O contact) for a 2 wire banjo pressure switch. So the original N/O contacts will be like for like, but because the N/C contact is no longer available I will have to link this out, but what is this actually used for? The black wire comes from the ECU (pin A06), will it bring up a brake switch fault if it doesn't see it operated? or will it affect the ABS? Any ideas?
