Yeah you need to flip the solenoid around. You have to run it backwards when installing on the rear brakes or you will run into the issue your having.

I am am still debating on running mine on the front brakes, it seems people are doing it without any ABS issues

 

Thats what I figured, damnit just when I thought I was done being covered in brake fluid. I dont have ABS in my truck, but I like the idea of regulating brake pressure to the front using the pedal.

 

On a 2013. Which line on the master cylinder send pressure to the front wheels. I have seen info on older models which it switches back and forth, depending on year, but can't find any block diagrams for a 2013
I have mine hooked up to the front line, wired up. I can hear the solenoid activate and I get the light for power sent to the solenoid. It doesn't seem to be working properly. I'm not getting any ABS lights so I don't believe the ABS to be causing the issue.
Pretty sure I'm on the wrong line but want confirmation before I start cutting lines again. Thanks for the help.
