i finished installing prosport water temp. gauge. Everything works perfectly other than the LED gauge light is on even when the engine is off.
This is how i did it.
There are two wires (black and white) from the temp sender. I hooked up the black wire to ground, and white wire is connected to green wire from the gauge. (followed instruction)
Red wire from the gauge was connected to the positive side of battery.
Black wire from the gauge was grounded.
White wires was not used since i only wanted amber LED.
Orange wire was connected to the blue/white wire from the back of the ignition key hole (the blue/white wire is really thick comparing to 24 gauge wires that i used). The instruction said to connect orange wire to headlight switch, however.
The LED won't turn off even when key is not in ignition.
So i tried connecting the white wire from the gauge to the ignition wire instead of the orange. The result was the same other than this time the LED is white instead of amber.
Did i mess up on hooking up wires?

I attached pics of the harness i took off from the ignition and the ignition wire

 

What ever you have hooked up to the battery change that to 12v switched that should work

 

should I connect the red wire (hooked up to battery now) to ignition wire and leave orange and white wires unconnected?
since orange wire is used to change led lights, and I want amber only, I'm assuming it's ok to keep it disconnected

 

what is the orange wire hooked up to? i dident read the whole thing before is the red saposes to be hooked up to switched 12v or constant?

 

right now, orange is hooked up to ignition wire.
the instructions says red should be hooked up to 12v accessory power. idk if it can be connected to ignition.

 

thats switched power hook it up to something that gets 12v when you put the key to accessory like the cigarette lighter and it should be fixed

 

wait so i keep the orange wire to the ignition wire ("12v power when lights are turned on"), and red wire goes to cigarette lighter?

 

they way my innovate is set up is theres a wire that you hook up to the headlights if you want them to dim with it if not you ground it or something but the red deff goes to switched

 

i hooked the orange and red wires on mine to the cigarette lighter fuse by the driver kick panel and mines orange all the time, turns off when the cars off

 

what is the orange wire hooked up to?

 

i finished installing. did not use the white and orange wires since i won't be changing LED back and forth
