Need Help with record player wiring/electrical

Hi this is my first post here I have a self contained record player. Its from the mid 70', in great shape and looks really cool. I want to use it to play records and also to play an ipod. It has a mic jack that I use to hook up the ipod. Everything is great except one detail I overlooked - anytime the the record player is turned on, the turntable i engaged. Picture it as the ipod playing nicely yet the tuntable is spinning the whole time. What I dont like about that scenario is that the turntable will be getting heavy use even when its not technically playing a record. So I am really hoping to come up with a way that to disengage the turntable yet still get power to the unit. I took the thing apart and inspected it last night. There are 2 and only 2 wires running to the turntable portion of the unit. My thought is that if I clip these wires and add a toggle on/off switch that i could power up the unit and then control the turntable separately with this new on/off switch. It seems kind of simple to me BUT I dont want to do anything stupid and ruin the entire thing. Also I have no idea if by adding a on/off toggle if somehow theres an unequal distribution of power that can cause problems...basically I dont know much!! so if anyone has any thoughts Id love to hear them! thanks so much. if anything is unclear I can post pics too if that would help. thanks so much! eric
