highly recommend this as well. it was even tough to fish this through the firewall with a coat hanger/electricians fish tape. be patient and dont be scared ripping your dash out. i was nervous too gutting out my dash on both sides to complete, but take your time and do a nice job while following the instructions and you shouldnt have any issues.
