2004 Ram 1500; Installing an electric brake controller. I got a wiring
adapter at u-haul and I found the pigtail under the dash behind the e-brake.
My problem is the blue wire is only putting out 2 volts at the pigtail. It
show 0 volts at the brake controller and at the 7 pin connecter at the
bumber. Is 2 volts normal or should it be 12v...any suggestions on a fix?
Thanks for the relpies, I fixed the problem. The 7th wire from the bumber
was not connected to the e-brake pigtail. Not sure if they come like that
from the factory or not, but once I connected the wire, everything works
