slots number 4 and 5 (from left)will be used to insert the two wires as shown in the pic below
Plz note that some audio controls have diff slots allotted in the clockspring. Best way to counter check all this is to make a small little cut on the wire of the grip in the middle/entry of the clockspring n use an ohm meter check if the contact b/w the input n output wires is present as US,euro n jap models may have diff clocksprings due to their own reqs.
