So I just installed a speedhut gps speedo and everything went great. That is until I tried to turn the car off once it was started. For some reason, the car simply wont turn off now the new gauge is installed without me pulling the power to MS directly. I hooked up the white wires to one of the old illumination light wires, the ground to ground of the rheostat. Left and right turn signals up to old left and right turn signal lights. And 12v to a direct line from the battery(with inline fuse). High beam I left unhooked until I could figure out what wire was the switch for it since the light in the gauge always has 12v going to it. Has anyone heard of this or might have an idea what might be causing it?
Oh before this the car worked normal and other than the key not turning anything off, still works normal
