Thanks for the quick reply. I'll see if i can find a manual at AutoZone or something tomorrow, hopefully that has the wiring diagram in it. I'll reply again with an update after i have some results.
EDIT: Got a manual at Autozone and it has a wiring diagram. First I'm going to check the shifter linkage, I've heard slack in the linkage can cause the switch to not complete its circuit, and if thats not the problem I'll change the backup light switch.
Thanks again
