I have a new S250 with the Deluxe instrument panel. I want to splice in for power to run a small amp and my Satelite radio. I would run power from my battery to the amp, but need to know which wires to use to send power to the amp and Sat radio when my machine is running. I want to use wires for the extra toggle switch locations by my wipers and fan controls. My Bobcat dealer sells that small low profile Jensen radio for about 300 dollars and are going to charge me 500 dollars to install. I am quite positive I can do it cheaper. Any help is appreciated. Bobby.
