Correct. The switch comes with this....

The switch only has a 6", if that, of wiring attached to it. The cable it includes has three bullet connectors at one end, that plug into the back of the switch. The other end is the two round connectors. You just trace the wires from your trim pump, and unplug the connectors, and plug in the switch to both sides. Piece of cake.
FYI---Head to Lowe's and buy some SS hardware. It comes with screws, but it isn't that hard to through bolt it. I used 2"
10-24 SS bolts, washers, and locknuts.
When I drilled through the gelcoat, I first marked all the holes, and then taped it off with the blue painters tape. Start drilling backwards with the hole saw, to avoid cracking the gel. I a big plastic bag down in the engine compartment to catch any shavings or dust that went down there. With the last boat I had my wife holding the bag...you don't want that stuff to get inside your bilge pump.
Now if only I didn't have to take my cover off and get into my boat to turn on my battery switch for this to work, I'd use it all the time and store it with my drive down.
