i have ps 2 machine running gt4 game. got a blue thunder racing wheel from dumpster. hooked it up with out foot pedals. reverse works. rear view works . gear change works. steering works. gas and brake won't work. went to options settings in gt4 set button choice. still no gas or brake. rather run it with buttons than foot pedals. am i missing something? the outer black cover on wire from whell is smashed open but no wires are cut. the green wire is smashed the most. tryed different button choices that didn't work. foot pedals are not hooked up.
