im trying to wire my 700r4 lock up to a toogle switch on the dash . i ran a 12volt power wire to pin A , grounded pin B ,and hooked pin D to the switch then the switch goes to ground .
my problem is every time i flip the switch to ground it , it blows the fuse .
does anyone know what the problem might be ?


sorry its not a 3rd gen its a 1989 chevy 1500 .
