Older nailers have a slide switch to select single shot or multi shot function of the nailer. That switch is part of the PCB Housing that you will be changing. The new PCB will have a push button switch that replaces the old slide switch. There is a clear rectangle plastic piece that fits in the same place in the body as the old black slide switch did. Instead of a slide switch you now have a push button selector switch that you must push and hold till you get a solid green light or a flashing green light that indicates single or multi shot function. To shut power off press and hold button till green light goes out.

Removed the housing, unplugged the old part and plugged in the new part. Hardest part is getting the housing and wires all back in the correct position. Take a picture of the wiring and part positions prior to removing part for re installation purposes.
