there are 2 cables both with 2 wires a black & a blue wirePic #3.
I can make out three wires on the bikes brake sensors. Black/Gnd, Blue/Sig & other Black (likely has another colour stripe unseen to donate 5v) please confirm . Connect to the three wire brake.
If you want to use the second brake sensor simply omit the 5v connection to the two wire connection.
Some connector or wire joining is needed,
Ok, the third which I thought is a reflection on the bike paint.there are 2 cables both with 2 wires a black & a blue wire
yes ill just use the rear brake which is the best connector to useOk, the third which I thought is a reflection on the bike paint.
You can still use both if you wish, on the 3 wire controller brake leave the 5v disconnected and it should work. Tbh only one brake cut out is often needed on the rear brake.
