I think i'm going to run mine right to the battery, that way i'm not taking power off no critical circuits, or hacking into any wires on the car. My dimmer i will take from the light on the ash tray tho.
how are you gonna get the gauge to shut off then??
guys, you can use two empty fuse slots in the fuse panel on the driver side kick panel.
there's two slots there with no fuse's in them. strip the wire an inch or so. melt some solder on the end to make it nice solid and slid it inbetween the two metal tabs that would make contact with a blade type fuse's tabs.
i've been running mine like that for almost two years now.
hope this helps.
I have my gauge hooked up as others have stated, with the red to constant power and the orange (only wanted the red display) to the green wire on the headlight dimmer. Turn on the car and the gauge comes to life, but no back light. Flip the headlights on and the display comes on. Turn off the headlights and display stays on. Now here is the weird thing. Started the car after work yesterday and the display lit up WHITE. The white wire isn't attached to anything!!! WTF??(freak)
Okay hopefully I can see what you did and figure out what I'm doing wrong.. I have tried wiring it up every way I can think of and nothing is working..
Wired the power wire to a positive wire on the cigarette lighter then tried wiring it to the fuse box.. Wired the ground to a negative wire, then tried grounding it to a bolt under the console.. I don't know what to do so any help will be great..
