clutch switch wires are under dash, if you had switch that clicks over master cyl. just unhook the yellow jumper that is there with green plug and plug it in. now under truck locate the plug that went into tranny that is round and has three pins in it cut it off and ground the center one, clutch switch should work. if your swap cam with all that it should you would have a small length of wire with the plug coming from the backup switch on the top of tranny, if not search around on here, roachie put a part number of the correct pigtail GM that will work. now hook those wires into the outer two wire from the tranny harness plug that you cut off. as for the ecm everyone that i have sold swaps to has always said the auto would work fine but you needed to swith to the manual if you wanted cruise to work (if you have it).
