Hello, New guy here . My 2007 ege bought used was missing the fuse compartment plastic panel door probably due to some work adding accessories. After some checking with a meter, I found a ground about 8 inches above the panel on the firewall with a 5/16 bolt sticking out. Added a ring connector and a 5/16 nut to it and got a good ground for my radar detector. Then checking the fuse box, fuse 33 "spare" is hot when the ign switch is turned on. So plugged in a "add a fuse" to 33 and wired it to pos on detector wire. Works perfect.
Now all I have to do is find a u pull it to replace the plastic trim panel. Also may need a trip to chiropractor after squeezing my fatness under the dash.
