    Just purchased Toyota harness # 3040P for Tekonsha P3 controller, when installed it would not power on. After checking the plug into the controller I found no 12V power in on the black wire, hooked to trailer have turn signals but no running lights. Can't find any blown fuses. Is this normal or am I missing something?

    I had the same problem when I installed mine. It turned out to be a blown 30A fuse in the block under the hood. All the fuses inside the cab were fine.

    Thanks for the reply, I checked under the hood replaced the #11 30A fuse although it appeared OK, found a blown fuse, labeled tow tail, unit still not powering on. I'm beginning to think unit may be bad, however last time I used it on my 06
    tundra it was working fine.
