ignition wires
 

Does anyone have a diagram or explaination on what wires are what at the ignition switch. I am hooking up an Apexi turbo timer and neex to know which wires are ignition 1 and ignition 2. I looked through the online verision of the workshop maual but was unable to find any clear diagrams. Probably my own ignorance, I am still learning at all of this. In my mind, I am trying to find out which wire comes from the power source and which one leaves to go to the starter. Thus ignition wire 1 and ignition wire 2 (going to starter). Any help is so appreciated as usual. Thanks
