To anyone who may know...I have a 2000 camtrakker w/Yashica camera. I need to know what each of the wires running to the camera is responisible for. For example, does the Yellow wire run to the shutter? There are 4 wires (red, yellow, green, black). Can anyone help me? I don't believe the red hooks into the camera. I sent this question to Camtrakker's customer service. Now, I wonder who gives the quicker response? Thanks for your help.
