How to Trim Seat Heaters for Installation
How to Trim Seat Heaters for Installation
Before installing the seat heater pads, carefully measure the area of the seat where they will be installed. The pads may need to be trimmed to fit your specific seat. If trimming is required, only cut along the top or sides of the pad. Do not cut or trim the end of the pad where the wiring exits, as this may damage the heater element.
