Consider getting the power from the cigarette lighter or the accessory outlet. However, the state of the power will not match that of your radio... so if that is a concern, you would NEED to tap it from the antenna lead of the MCS.What's the best way to add a FM Modulator to the MCS radio? Should the power and ground wires be tapped off the MCS harness or is it better to go through the fuse panel? Anyone have the pin out for the fuse panel? Thanks.
