This all depends on which switch you have bought for it: some of them come with 2 Black wires. One of those goes to the RUN/OFF switch and the other to the START button: this latter one also powers the headlight when the START button is not pressed. Some switches instead have 1 Black wire, feeding both of these circuits.
The START button for the K6 must have an isolated Yel/Red wire coming from it to the Start solenoid (sometimes they use a Green/Red instead for this circuit). The Grn/Red wire on the Start solenoid then goes to your 'safety module', or else you can connect it to the Green wire that is loose under the left side cover. This last step will let it start in gear or without pulling in the clutch, as it bypasses the 'safety module' (more like normal motorcycles...).
If the START button has just one wire to it (Yel/Red), then the Grn/Red solenoid wire must be connected to a Black wire under the left side cover instead. In this case, the START button does NOT power the headlight, so you will have to power it another way...
