I have a 2001 mercury sable ls and i ran all the wires from the deck to the amp which is in the trunk of my car; the system control wire, rca cables and the remote cable and everything. Everything except the system control wire is connected to the deck, every things set up on the amp. All i need to do is hook up the system control wire to the deck, but i don't know where it's supposed to go on the back of the deck. Also i don't have the power cable hooked up to the battery. I know it's gotta go through the firewall or something; one, i don't even know where that's located; and two, do i need to drill a hole?
The system control wire should go to the remote wire on your pioneer and it is probably blue as well. The firewall is the metal wall that seperates you from the engine. You may have a rubber grommet that you can use already there, you just need to cut a hole in it and pass the wire thru. If you have to drill a hole, use a punch and hit it with a hammer to mark where you want to drill. Then check the other side to make sure there is nothing in the wy. Using a sharp bit drill the hole. Place a grommet of the appropriate size in the hole to protect the wire from getting cut by the sharp metal and pass the wire thru the firewall. Make sure to put a fuse within 18 of the battery.
