So I installed everything and was just using the obdII port and the gauge powered up but wasnt run off the ignition so the gauge would stay on, so i tapped into the pink wire. When i started the car everything worked but when i turned the car off to see if the gauge would turn off, the car stayed on. I could take the key out and the car stayed on. When i disconnected the red power wire from the spliced pink wire i could turn the car off. So i need help wiring this to the ignition because i dont wanna have to unplug the gauge from the obdII to turn it off.

 

theres other power sources u can wire it into... my friend used the windshield wiper fuse lol

 

what gauge wire did you use? where did you run it?

 

i forgot where i ran mine.. but mine turns off right when the car turns off and when i start the car the gauge doesnt come on for about 3 seconds

 

ive got the add on to do it, i just need to figure out how to run it and wich fuse to use, ive got 18 gauge wire as well

 

what year is your car? that matters in how you have to wire it.

 

09 the only year they made lnf sedans

 

The LNF shouldn't need a wire run to it, you should be able to start it up and the gauge starts about 10 second after.

Also if you do run a power wire to it you'll need to remove the red jumper, and it should shut off when you turn the car off.

if you have an lnf it should be "can" gauges which require not external power as it gets the power from the obd II port. The LSJ uses the PT set of gauges which require external power.

 

yeah in my HHR SS i only have it plugged to my OBDII and they turn on a few seconds after the car and turn off like a couple minutes after i turn the car off

 

ok the obdII powers it but it doesnt shut off right away it must take a bit to shut off, and no i never removed that jumper

 

well i guess it just takes a couple of minutes to turn off, so i cut the power wire to my boost gauge up for no reason
