andy from ultimarc emailed me back.. he said he sold them in 100 pack, (i tried looking on home depots web site couldnt find them) he also told me to try first using a pair of pliers to open up my existing ones.. i don' know how i'm going to do that its all tight. I bought the control panel which was pre-built i don't know anything about cutting, stripping, and crimping wires and re-connecting to the new .250 quick disconnects properly.. but looks like im going to have no choice but to learn.
