Help guys i followed the instruction posted above but I cant get my gauge to work this is what i have done so far, gave the gauge power and routed a vacumm line thru the back end of the glove compartment and cut the vacumm line shown in the pictures....what im i missing? i have been doing this for 2 hrs ...any help?

 

Can you give me an idea of how you got power and ground to it?

 

Problem fixed ....kinked line.

 

Glad you got it working. My only suggestion would be to ziptie all of those vacuum lines especially since it appears that you tapped from the line coming of the fpr. If that pops off then your are in trouble...other than that it looks clean and im glad to see its working!
