what color wire goes where in installing an output jack? what color wire goes where in installing an output jack? Hi Guest Wires will often be different colours but the way to wire the output jack is as follows. from the earth terminal on the jack, run a wire to the ground which is normally on the top of the Volume pot. Then from the positive (Or live) side of the jack run a wire to the Middle terminal of the Volume pot.
