Cut the new EL tape the same length as the original or slightly longer. In my case I cut it about a half inch longer. Then cut your colored film (if you needed it) the same size as the EL tape strip to be installed. It can be slightly narrower than the tape. I cut mine about 7/8 of an inch wide and the full length of the strip.

Also, because I had them install the connectors, that part of the strip is much thicker than the original, so I had to cut out some plastic to make room for the difference.


Now simply lay in the new EL tape and it's film (if applicable) and reassemble the sill plate to it's plastic/rubber base.

If you are having problems getting things to line up, you can always use clear tape to hold the EL tape and it's film in place for assembly.

Next, I attached the original wiring pieces to the new EL tape wires. You can probably skip this step, but I felt I should keep the original wiring and break away plugs.


I also cut the wiring from the original yellow inverter box and attached it to the white wires (output) of the new inverter.
