SWI-PS, Do I have to cut wires, is there a harness?

[control]

I have the harness for the main adapter, but it seems a shame to tap into the 2nd 20 pin connector just to get the three wires, I would much rather but a harness so that I am not changing anything on the factory harness, I looked but only the main harness adapter seems to exist, any ideas or sources for this item? Thank you

PAC includes a harness for the SWI-PS with the correct connector and resistor in their TATO kit. If you don't need the JBL module maybe you could contact them and see if they'll sell just that harness.
