I took a Uhaul electric trailer brake controller from my old tow vehicle and installed into a 2016 Frontier that has a factory equipped tow package. I bought a sub-harness from my Nissan dealer, and plugged that in under the dash. I made the necessary splices from the sub-harness to the Uhaul "Activator II" brake controller. There is power at the controller, but the output for the electric brakes is only 1.6 volts. Is that the correct voltage? I have seen in other forums that there may be an additional relay that needs to be installed, but that seems to be for older Frontiers, and I also looked under the hood and it seems like they are all there. Can anyone help with this?
