Thanks, I'll take a look at the e-brake switch this weekend.

I also just learned it could be a bad $30 brake fluid sensor. I wonder if there's a way I can test this sensor with a voltmeter before purchasing it...

If it all worked fine before LED install I would suspect something with the LEDs is causing this. The cheapest thing to do is put all the old bulbs back in and see what happens.

Not sure about the 2009s but on my 2004, I took out the side panel that is on the end of the dash (drivers side, faces the drivers door). Had the stock blue flasher module right there, reached in, took old one out, put new one in.

I believe the 09+ are different and you'd need to add resistors on those trucks. Have a look on the 09-14 part of this forum to verify.
