I appreciate the information and the heads-up on the washers Regor. The plug I have looks like the first pic Wicc_ed. I taped up the wires with black electrical tape so hopefully that will hold for the time being. If I have to solder them...I have to tear apart the garage to find the solder.
I am still learning that electrical work is more than just electrocuting myself putting up Christmas lights.
I almost have two more skulls ready to hook up. I think I will just wait until they are wired up and then test it out using one of the VSA programs the good Capt'n has put together.
Thanks again.
