I was thinking of replacing a couple of my switches that are not command equipped with new command switches. After looking at how little used switches are going for and the hit that I'd take on them, I thought twice. Then I spotted the ERR Switch Commander. This $24.95 kit will convert a remote control Fastrack switch into a command model. The install is a piece of cake, and it works just like the factory command switches.
Here's the manual.
ERR Switch Commander Installation Manual
This is what the ERR board looks like, you install this into an existing slot in the base of the Fastrack switch.
You plug in a connector, splice one wire, and drill a 1/8" hole to mount the switch. Put the back on the switch and you have a command switch in about 15 minutes! I think the hardest part is taking all the screws out to remove the bottom plate, then putting them all back in!
Here's the upgraded switch. The only difference between this and the factory switch is they used a green button for the PGM button. I'll take it. A nice quick way to have command switches without the hassle of trying to dispose of the old ones and buy new.
