I have built both kits,2T-gen and CP1. How do I connect to mic input? Do I get another mic connector and use a pin to attach test probe or what. Not finding any thing in hand book regarding coupler and 2T -gen.Wish there were directions on how to hook up and use as well. Never did this before and want to learn.This would be more fun if I knew how to use. tnx for any input.
