Randy-I do not recommend cutting off the speedo switch. It limits you to only using the reciever pack. Last season at a couple of club races I was unable to get the reciever pack charged so I just used the race batt to power everything for that run. Sometimes the little reciever packs false peak. I don't see that saving 2 or 3 grams on the switch is worth losing the insurance of being able to run the speedo normally, and you dont have to solder a new switch if you run that speedo in another car or sell it.
