Only needs to go up to 15 PSI, but need wide enough separation between numbers so can see the difference between one number and the next. Want mechanical boost gauge, not electric or LCD. Where do I find this? Thank you!

 

I instaled a VDO boost guage in my supercharged '07 GT, as I wanted the same wide seperation that you do. It's 2 -1/16"...

Thanks, Brian. VDO just released a similar gauge, PN# 1501911. It has the same 15 PSI sweep, but is backlighted and has a nice chrome ring to match our vents...looks almost custom-made for our Stangs! Summit and Jegs carry them...

 

Excellent! The chrome rings will look great. Mine was backlight, too (I wired it in with the headlight switch).

 

Do you know what the wire colors are to hook to the headlight switch? (what color goes to what?)

 

It's been so long since I installed it that I've forgotten. Try the link below in your quest...

There's a reference to wiring into the headlight switch there.

 

I have the roush led gauge and for nighttime color i connected it to the headlamp switch purple with grey stripe. Comes on whenever I turn lights on

 

Where did you tap in for the vacuum line?
