You don't really have to see it to install it. You can install it by feel pretty easily.
If it's like the one I just installed,it has 3 wires to it,and does go on the back of the heater plenum. Reaching back just left of the heater motor,you'll feel a rectangular hole with 2 tabs sticking out. The coil sring side goes into the hole,and the board snaps into the tabs.(tight fit-you may have to pry on the tabs to get the board to snap in.) Then just connect the 3 wire plug and it works.
