I have just installed an electric brake controller on my 2006 Silverado 1500 and am not getting any voltage to the controller. I have installed the 40 amp fuse to the #1 Stud position in the box under the hood as per instructions from the harness provided with the truck. I still have no voltage reading on the red or blue wire connections under the dash where the trailer brake harness connects too. Any clue?

When I first started towing a horse trailer and subsequent trailers since I had a habit of pulling the wires through the frame. I found out later that i was knocking the insulation off and usually ended up with a bad GROUND.
I believe you have two grounds on your unit.
Try checking continuity on all your wires inadditon to the fuze's.
It can be a real headache.
Good Luck,

Does your controller have an internal fuze.
It's been a long time since I played with controller.
Are you connecting to the brake switch/wire for power?
I would jumper directly to the battery to see if I get power to the unit.
Just random thoughts hope one of them helps

Not sure if things have changed but when I did one of my chevys I had to find the power wire for the power to go to the controller in addition to installing a fuse, wire was folded up and taped to harness next to the box with the fuses under hood.
