i ran everything fine, and it reads right, but i cant get the gauge to shut off with the car it just stays on all the time. i ran it to where my other gauges are connected which is the factory clock location. any ideas? i know the red wire is power, black is ground but what do i do with the white and blue, i have no install guide so i cant look at that and im having a hell of a time getting it to shut off with the car..

I found this from a Supra forum:

RED: 12v power
BLACK: chassis ground
WHITE: 0-5v output
BLUE: serial output

On the gague connector, they go (looking at the back, with up being up):
Brown | Black | Green | Red | Orange | White ||| Red | White | Blue | Black

ya but if i hooked them up the same way with the power and ground and i switched the middle wires a lot to see if it would work, why wouldnt it shut off with the car?

that diagram doest make the most sense either lol, is that the wiring on the back of the wideband or back of the clock

you need to hook it into the yellow wire. which is 12 volt ignition......red is constant 12 volts.
