When I first purchased my car it came from with a boost gauge unistalled. I want to reinstall it but I'm kinda stuck on where to wire everything.



My question is where do the orange and white wires go and if they even need to be hooked up at all? I know the red I can tap into the instrument cluster fuse and the black is just a ground. This is a defi gauge. Thanks

Thanks!

 

So I got the gauge installed but when I turned the car on, I couldnt roll up the windows disconnected the gauge/add-a-circuits and plugged the fuses back in, the windows worked fine.

I used two add-a-circuits one for power which was linked to the instrument cluster fuse and the ign to the cigarette fuse. I added another 7.5 fuse to the add a circuit which was plugged into the instrument fuse (making it two 7.5's plugged into that spot) and the windows worked fine, is this a bad thing to do?

Also when I went out to test the gauge the car threw two code p0462 and p0500. Should I be worried? I ended up clearing the codes...
