Is there any reason I could not install both symtec heated grips and the BurnsMoto USB outlet to the existing heated grip accessory line? Figure since that line is already switched power and fused that I could run both items off of it without issue or would it draw too much power over that circuit? I have read that since the USB necks down 12v to 5v via a resistor, you need to have it on switched power or it will drain your battery. If this is a bad idea, I could probably vampire clamp into the license plate light for the USB? Must be under the seat somewhere right?

Thanks for any suggestions or input.

USB 12 down to 5 via a resistor

I think not - a solid state voltage regualtor on a chip is used (low power) -

keep the USB on a separate circuit, so if your heated vest blows a fuse you can still run your GPS or whatever you plug int to the USB

Yeah, I certainly hope it doesn't use a resistor to reduce the voltage. I wouldn't buy that accessory if it did -- you don't really want the voltage to your USB device fluctuating with the revs.
