having trouble finding a ground source for my new gauges (boost and a/f )

im using the middle ignition "square thingy" from the fuse box, but i can't find a ground. preferably not one where i have to take out the dash to access.. cuz i HATE HATE HATE taking out EG dashes

 

any metal connecting to the frame should work.. there's plenty of ground around the radio.. just remove the middle dash and you should find it...

or go under dash and look for ground there
