switched power/old phone plug
 

I took the phone out of my dash on a 1994 sl500. Does anyone know if there is a plug that can be used on the existing wire that will give me a switched power. I plan to put my V1 remote and the laser jammer in the space. I was hoping that there is an adaptor so that I could get my power from it just like the phone did, not sure if I should plug into the one on the right or left, yet. Thanks Dairel
