Looking at videos they have to come apart and I can't get them apart, no room to get a good grip on them. I moved all I could out of the way but they won't budge. I could try to switch them, just no room to work. Thanks for the replies.
they are tough to get to and I can't get them apart pressing the tab on it but it won't budge any ideas, don't want to brake any wires. Thanks for the reply.
