Bake controller

[hvrsq]

I have and 05 hoe with tow package. I just purchased a a brake controller and dont know where to plug it in at. I found the fuse box but there are 4 empty spaces and I dont want to plug it in to the wrong one. And I bought it used so no owners manuel.
THanks

There is a plug under the dash on the drivers side but you will need the wiring harness that came with the vehicle if its not in there you might have to go to the dealer to get a new one. All you have to do is wire it to the harness and plug the harness in.
