i just started on lighting. i want to check my back up lights on my 79. i see on the diagram its circuit 24 light green. i need to know how i can test that. how do i make these work without the borg warner in? how do i make em work after tranny install? i know theres a clutch switch on the pedal but what controls the lighting of the whites? any direction will be appreciated. and maybe a pic of what controls the lighting. dont even know what it looks like or where its installed. this baby didnt make it to me whith that part i guess.
