Just to start this thread i did search for this topic! I am installing my race radio (2 Meter) and I need to find a way to run my wires thru the firewall to connect to the battery! I own a 2004 f-150 extended cab and installing the radio on top of the dash with my offroad GPS! I would also like to thank ScottFcasni for the write up on how to remove the panel for the radio cause that will save me alot of time when installing the radio and so forth! thanks for your time!
