I'm about to read through that but the stock HU has a ground going into the mounting brackets around the stereo, its the little plug on the right of the bracket that proves to be a PITA when installing a HU in these cars. EDIT: That site didnt have much info on the install, you should be good if you just splice the right wires and plug that ground back into the stock brackets. Thats what I did and I'm running an Alpine that recommends additional power/ground wiring for the high power internal amp.
right now the ground is dangling back there with its plug still intact. So it was just an extra ground? nothing else is connected to it?
