I've been wondering how to hook up a tach to my truck 2wd.It is a 1993 toyota, has speedo ,temp gauge and fuel level. I know you hook up the positive wire to the coil. the coil is different on a 1993. it is not the standard coil that is on most toyota trucks. the coil is not round it is block shape. pictures would be good
