Brake Master cylinder connector?

Looks like the master cylinder is toast, so I am replacing it and bleeding the new one. I noticed that the old one had no connector plugged in. Do some of these have a place for a connector but not a harness to it? I saw couple of lines that were cut underneath it but looks like an extension wire that were spliced, but no connector to the wires, could be going to it or to somewhere else as this truck had so much extra wires for speakers, amps, extra-large fuses by the battery, etc. If there should be a plug, is it sold separately and what color are the original wires going to the cylinder?
