Ok, hadn't seen much on this, mostly for older models, but if you're wondering where to tap into for your boost/vacuum gauge for your 2013/2014 then this is the best spot. I tried off the passenger turbo tube, but it wasn't accurate and it didn't read vacuum there either. This spot was...

I have seen some of the other gauge colors that are in the 2011-13 F150s and there is a color difference. I have a Blue Flame FX4 and it came with red needles and accents. Has anyone changed the needles or done a full swap to the blue XLT gauge set up?
