So I have fully installed and wired almost all of my gauges, Autometer Factory Match GM's... I am stuck on which wires I am suppose to tap into for my Fuel Rail Pressure Gauge. Autometer instructions say for 06-08 Chevys the postive wire goes to the yellow wire on the HPOP sensor and the ground wire goes to the orange/black wire... For the 09 Chevys and up it says the postive wire goes to the orange/black wire and the ground wire goes to the white wire. I have tried this both ways and neither is allowing my gauge to work. The 2nd way made my gauge stay on 0 like it was grounded and the 1st setup rotated the needle all the way to 30 and stay and nether way made the needle move. Has anyone wired a Fuel Rail Pressure gauge on an 08 LMM Duramax and know which wire goes to which cause I am stuck THANKS!!!
Below is a picture of where I first tried wiring it in... Double checking with y'all to make sure I am tapping into the right wires and correct area...
