i just changed starter/solenoid in 77 280z, marked wires b/4 disconnect- but they rubbed off. unable to get either good view/ info from photos or repair man. one battery term has 3 wire connect from wiring harness running on top of fire wall(i assume this is positive lead?). the other has heavy gauge wire (i assume to ground/ starter bolt). ANY help with connections, greatly appreciated. also,help with solenoid connections.THX.
